721ad4aa18 [AArch64] Add SME implementation of ScaleUVRowDown2Box
There is no benefit from an SVE version of this kernel for devices with
an SVE vector length of 128-bits, so skip directly to SME instead. We do
not use the ZA tile here, so this is a purely streaming-SVE (SSVE)
implementation.

5c12e0b2de [AArch64] Add SVE2 implementations of HalfFloat{,1}Row
For HalfFloat1Row, SVE has direct 16-bit integer to half-float
conversion instructions so there is no need to widen to 32-bits.

For HalfFloatRow, SVE zero-extending loads avoid the need for seperate
UXTL(2) instructions.

Observed reductions in runtime compared to the existing Neon code:

            | HalfFloat1Row | HalfFloatRow
Cortex-A510 |        -38.3% |       -17.3%
Cortex-A520 |        -37.6% |       -18.8%

432d186116 [AArch64] Add Neon dot-product implementation for ARGBSepiaRow
We can use the dot product instructions to apply the coefficients
directly without the need for LD4 de-interleaving load instructions,
since these are known to be slow on some micro-architectures.

ST4 is also known to be slow on more modern micro-architectures, however
avoiding this is left for a future SVE implementation where we can make
use of interleaving-narrowing instructions.

fc94178260 Implement I010ToNV12 conversion
I010, also known as YUV420P10, is 10 bit YUV pixel format with 3 planes.
Both I010 and NV12 are 4:2:0 subsampling. NV12 has a Y plane, and an
interleaved UV plane.

32ccd53bb3 Add P010ToNV12 to convert 10 bit biplanar to 8 bit biplanar
- P010 and NV12 have the same layout: Full size Y plane and half size UV plane.
  P010 and NV12 are 4:2:0 subsampling
- P010 uses upper 10 bits of 16 bit elements
- NV12 uses 8 bit elements
- The Convert16To8 used internally will discard the low 2 bits.
- UV order is the same - U first in memory, followed by V, interleaved
- UV plane is be rounded up in size to allow odd size Y to have UV values
- Similar code could be used to convert P210ToNV16, P410ToNV24, with the size
  of the UV plane affected by subsampling 4:2:2 and 4:4:4 variants.

b5f9d7cb76 [AArch64] Add SME implementation of TransposeUVWxH
We can make use of the ZA tile register to do the transpose and
de-interleaving of UV components without any explicit permute
instructions: the tile is loaded horizontally placing UV components into
alternative columns, then we can just store the independent components
vertically.

a64fffe632 Revert "Disable NV12ToARGB_SVE2 which fails the 'any' test"
This reverts commit f480fa1c4a4af0ce3c34cd7b1ab0d85f1a36ce17.

This code has a number of small issues:

* The YUVTORGB_SVE_SETUP macro requires p0 to be initialized to
  all-true, however the existing kernel does not initialise p0 until
  after this macro is called, so flip the order.

* The p2 register is missing from the clobber list, so add it.

* The existing code uses the wrong condition flags when determining
  whether to do the tail iteration using WHILE instructions or not.
  Additionally the number of tail iterations is incorrect, as it was
  incorrectly not changed from when the tail code was always executed.

While we are here, make another few small improvements:

* Remove the single-quote digit separators as requested here:
  https://chromium-review.googlesource.com/c/libyuv/libyuv/+/5622133

* Remove "volatile" from the asm block counting the vector length.  This
  particular asm block cannot be removed by the compiler since the
  output register is consumed by subsequent code, so "volatile" is
  unnecessary here and we remove it.

* Add some additional empty comments to force clang-format to put macros
  into the next line rather than on the same line as other asm.

367dd50755 [AArch64] Add SVE2 impls for {UYVY,YUY2}ToARGBRow
This is mostly similar to the existing NV{12,21}ToARGBRow_SVE2 kernels
except reading the YUV components all from the same interleaved input
array. We load four-byte elements and then use TBL to de-interleave the
UV components.

Unlike the NV{12,21} cases we need to de-interleave bytes rather than
widened 16-bit elements. Since we need a TBL instruction already it
would ordinarily be possible to perform the zero-extension from bytes to
16-bit elements by setting the index for every other byte to be out of
range. Such an approach does not work in SVE since at a vector length of
2048 bits since all possible byte values (0-255) are valid indices into
the vector. We instead get around this by rewriting the I4XXTORGB_SVE
macro to perform widening multiplies, operating on the low byte of each
16-bit UV element instead of the full value and therefore eliminating
the need for a zero-extension.

Observed reductions in runtimes compared to the existing Neon code:

c8974cf8d4 [AArch64] Add SME feature detection on Linux
This commit just adds the kCpuHasSME to represent that the CPU has the
Arm Scalable Matrix Extension enabled, but this commit does not
introduce any code to actually use it yet.

Add a test to check that the HWCAP value is interpreted correctly.

96bbdb53ed [AArch64] Add SVE2 implementation of I422ToRGBARow
This is almost identical to the existing I422ToARGBRow_SVE2 kernel, we
just need to interleave differently for the output.

The RGBA format actually saves us an instruction compared to ARGB since
there is no need to merge in the alpha component, we can just replace
the odd elements of the alpha vector itself during the narrowing.

Also rename some existing macros to make more sense when distinguishing
between ARGB and RGBA.

004352ba16 [AArch64] Add SVE2 implementations for AYUVTo{UV,VU}Row
These kernels are mostly identical to each other except for the order of
the results, so we can use a single macro to parameterize the pairwise
addition and use the same macro for both implementations, just with the
register order flipped.

Similar to other 2x2 kernels the implementation here differs slightly
for the last element if the problem size is odd, so use an "any" kernel
to avoid needing to handle this in the common code path.

Observed reduction in runtime compared to the existing Neon code:

4f7fd808b7 [AArch64] Use full vectors in TransposeWx{8 => 16}_NEON
The existing Neon code only makes use of 64-bit vectors throughout which
limits the performance on larger cores. To avoid this, swap the Neon
code from a Wx8 implementation to a Wx16 implementation and process
blocks of 16 full vectors at a time.

The original code also handled widths that were not exact multiples of
16, however this should already be handled by the "any" kernel so it is
removed.

Finally, avoid duplicating the TransposeWx16_C fallback kernel
definition in all architectures that need it, and just put it once in
rotate_common.cc instead.

Observed speedups for TransposePlane across a range of
micro-architectures:

 Cortex-A53: -40.0%

6f1d8b1e11 [AArch64] Add SVE2 implementations for ARGBToUVRow and similar
By maintaining the interleaved format of the data we can use a common
kernel for all input channel orderings and simply pass a different
vector of constants instead.

A similar approach is possible with only Neon by making use of
multiplies and repeated application of ADDP to combine channels, however
this is slower on older cores like Cortex-A53 so is not pursued further.

For odd problem sizes we need a slightly different implementation for
the final element, so introduce an "any" kernel to address that rather
than bloating the code for the common case.

Observed affect on runtimes compared to the existing Neon kernels:

             | Cortex-A510 | Cortex-A720 | Cortex-X2

f5882ed1c5 [AArch64] getauxval(AT_HWCAP{,2}) feature detection, attempt #2
This re-lands commit ba0bba5b2b7e38c9365a5d152b4efa0458863213.

Now with additional #ifdef __linux__ guards to avoid compiling
Linux-specific code on non-Linux platforms. Non-linux feature detection
will be added in a separate patch.

Using getauxval(AT_HWCAP{,2}) has the advantage of also working under
emulation where faking /proc/cpuinfo is not supported.

For the Chromium sandbox, getauxval is supported since API version 18.
The minimum supported API version at time of writing is 21 so we should
be able to use getauxval unconditionally. On the off-chance the call
fails it will return 0 and we will correctly fall-back to using only
Neon.

If we want to read the current CPU implementer or part number we could
do this by checking HWCAP_CPUID and then reading MIDR_EL1. This will
cause a kernel trap to emulate the EL1 read but should still be a lot
faster than reading the whole of /proc/cpuinfo.

3af6cafe8d [Arm] Don't expose DotProd kernels, fix CMakeLists.txt
Don't define HAS_*_NEON_DOTPROD for 32-bit Arm platforms, since they are
only defined in *_neon64.cc for now.

Also define -DLIBYUV_NEON=1 and pass -mfpu=neon to *_neon.cc for 32-bit
Arm platforms, since otherwise __ARM_NEON__ is not defined.

Also fix a typo: ly_lib_static should be ly_lib_name in the name of the
common object files. The existing code happens to work since they are
defined to the same thing.

e52007eff9 [AArch64] Add SVE2 implementation for I444ToARGBRow
Being able to use SVE2 functionality for these kernels has a number of
performance wins compared to the existing Neon code:

* For the Y component calculation we are able to use UMULH, versus the
  existing UMULL x2 + UZP2 sequence in Neon.

* For the RGBTORGBA8 calculation we are able to take advantage of
  interleaving narrowing instructions, allowing us to use ST2 rather
  than ST4 for the store. This is a big performance win on some
  micro-architectures where ST4 is costly.

* The use of predication means we do not need to add "any" kernels, we
  can simply rerun the calculation with a not-full predicate for the
  final iteration.

To avoid the overhead of generating a predicate register on every
iteration we duplicate the loop body and only generate a predicate on
the final iteration of the loop. This costs a small amount on the final
iteration but should still be significantly quicker than the overhead of
a function call needed by the "any" cases. Duplicating the loop body to
reduce the use of the WHILELT instruction improves little core
performance by ~12% by itself but has negligable impact on other
micro-architectures.

Reduction in runtime for the new SVE2 implementation compared to the
existing Neon implementation on selected micro-architectures:

Cortex-A510: -36.5%
Cortex-A720: -17.3%
  Cortex-X2: -11.3%

f2e78e1304 [AArch64] Use Neon dot-product instructions in ARGBToYMatrixRow
Using the dot-product instructions here allows us to avoid needing LD4
for loading individual colour channels, which gives a big benefit on
some micro-architectures where such instructions perform significantly
worse than LD1. In addition the dot-product instructions have higher
throughput compared to the Neon

Observed reduction in runtimes for selected kernels moving from *_NEON
to *_NEON_DotProd:

     Kernel | Cortex-A55 | Cortex-A510 | Cortex-A76 | Cortex-X2
ABGRToYJRow |      -6.5% |      -22.5% |     -43.5% |    -71.2%

a038cda7b8 [AArch64] Enable detection of additional architecture features
In particular there are a few extensions that are interesting for us:

* FEAT_DotProd adds 4-way dot-product instructions which are useful in
  e.g. ARGBToY.

* FEAT_I8MM adds additional mixed-sign dot-product instructions which
  could be useful in e.g. ARGBToUV.

* FEAT_SVE and FEAT_SVE2 add support for the Scalable Vector Extension,
  which adds an array of new instructions including new widening loads
  and narrowing stores for dealing with mixed-width integer arithmetic
  efficiently and predication for avoiding the need for "any" cleanup
  loops.

This commit simply adds support for detecting the presence of these
features by extending the existing /proc/cpuinfo parsing, splitting it
into separate Arm and AArch64 functions for simplicity.

Since we have no space left in the bitset entries between Arm and X86
entries, we reuse some of the X86 entries for new AArch64 extensions.
This doesn't seem obviously problematic as long as we avoid setting
kCpuHasX86.

f0921806a2 Disable NEON if memory sanitizer is enabled
- MSAN fails on most inline assembly, unaware of what the load and store instructions do.
- MSAN is also failing on row_any functions, which memcpy a correct number of pixels into a buffer that is SIMD vector sized, apply SIMD to the full vector, and then memcpy the exact number of resulting pixels to the output buffer.  MSAN wants the temporary buffer to be initialized.  Which genenerally is done with a memset(buf, 0, sizeof(buf)); to satisify MSAN.
- RVV may not require disabling MSAN, since row functions are all 'any' number of elements, and implementation is intrinsics.

10de943a12 [RVV] Enable ScaleRowUp2_(Bi)linear_RVV/ScaleUVRowUp2_(Bi)linear_RVV
ScaleUVRowUp2_(Bi)linear_RVV function is equal to other platforms' ScaleRowUp2_(Bi)linear_Any_XXX.
We process entire row in this function.
Other platforms only implement non-edge part of image and process edge with scalar.
ScaleRowUp2_(Bi)linear_Any_XXX: Combine ScaleRowUp2_(Bi)linear_XXX(non-edge) + ScaleRowUp2_(Bi)linear_C(edge) by SBUH2LANY/SU2BLANY.

* Run on SiFive internal FPGA:

Test case                       RVV function			Speedup
I444ScaleFrom640x360_Bilinear	ScaleRowUp2_Bilinear_RVV	8.21
I444ScaleFrom640x360_Linear	ScaleRowUp2_Linear_RVV	        8.08
