ba0bba5b2b [AArch64] Use getauxval(AT_HWCAP{,2}) for feature detection
This 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.

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%
 ABGRToYRow |      -6.5% |      -22.5% |     -43.5% |    -68.3%

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.

ec2e9ca000 [RVV] Support AR64ToAB64 and RGBA-family color conversions
Add scalar code for AR64ToAB64, ARGBToRGBA, ARGBToBGRA, ARGBToABGR, RGBAToARGB, BGRAToARGB, and ABGRToARGB.
They are originally implemented by ARGBShffle.
This CL independetly implements them, and only enables for risc-v now.
This CL also add RVV implementation for `RGBA-family <-> RGBA-family` color conversions.

* Run on SiFive internal FPGA(VLEN=128):

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.

ScaleUVRowUp2_(Bi)linear_RVV function is equal to other platforms' ScaleRowUp2_(Bi)linear_Any_XXX.

964d963afb Enable I422To{ARGB,RGBA,RGB24}Row_RVV
Run on SiFive internal FPGA:

I422ToARGB_Opt (~10x vs scalar)
I422ToRGBA_Opt (~10x vs scalar)
I420ToRGB24_Opt (~8x vs scalar)

LIBYUV_WIDTH=1280 LIBYUV_HEIGHT=720 LIBYUV_REPEAT=10

This CL manually sets rounding mode,
since we use fixed-point vector narrowing clip.
There is no definition about default value for fixed-point rounding mode.
https://github.com/riscv/riscv-v-spec/blob/master/v-spec.adoc#38-vector-fixed-point-rounding-mode-register-vxrm
The behavior could be different on differet paltforms. To avoid unexpected behavior, we set rounding mode manually.

f4bd840794 Fix compile error for riscv scalar & simplify cmake cross build flow
1. Fix compile error when build riscv without using vector

2. Fix run_qemu.sh misused v=true for USE_RVV=OFF case

3. [cmake] Fix warning by rename TEST to UNIT_TEST
Warning log:
CMake Warning (dev) at CMakeLists.txt:57 (if):                                                                                                                                                                                                                  [54/1931]
  Policy CMP0064 is not set: Support new TEST if() operator.  Run "cmake
  --help-policy CMP0064" for policy details.  Use the cmake_policy command to
  set the policy and suppress this warning.

  TEST will be interpreted as an operator when the policy is set to NEW.
  Since the policy is not set the OLD behavior will be used.
This warning is for project developers.  Use -Wno-dev to suppress it.

4. [cmake] Simplify logic for cross-build
