The Neon dot-product instructions perform two widening steps rather than
one, saving us the need to widen the absolute difference to 16-bits
before accumulating. Additionally, the dot-product instructions tend to
have better performance characteristics than traditional widening
multiply instructions like SMLAL used in the existing
SumSquareError_NEON code.

The MOV instruction is an alias of ORR where both registers are the
same and should be preferred.
Both ORR and MOV are not zero-cost instructions on all
micro-architectures so there may be better ways to express these

The "memory" clobber needs to be present even if the asm does not store
anything to memory, since otherwise the compiler would be allowed to
reorder earlier stores to the pointers after they would be needed by the
asm.
Also fix up the zero-initialisation of accumulators in
SumSquareError_NEON, since EOR'ing a register by itself is not a
recognised zeroing idiom on most AArch64 micro-architectures.

The existing code performs a lot of shifts and combines the R and B
components into a single vector unnecessarily. We can express this much
more cleanly by making use of the SRI instruction to insert and replace
shifted bits into the original data, performing the 5/6-bit to 8-bit
expansion in a single instruction if the source bits are already in the
high bits of the byte. We still need a single separate XTN instruction
to narrow the B component before the left shift since Neon does not have
a narrowing left shift instruction.

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.

* FEAT_DotProd adds 4-way dot-product instructions which are useful in

* 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.

The existing Neon code makes use of a pair of UQSHRN and UQSHRN2
instructions to extract the top half of a widened multiply result.
These instructions would ordinarily saturate, however saturation can
never happen in this case since we are shifting by 16 to get the top
half of each element, the top bits remain as-is.
We could move this to using a slightly simpler non-saturating shift,
however in this case it is simpler and faster to just use UZP2 to
extract the top half of each 32-bit lane directly.

The existing code makes use of a pair of lane-indexed load instructions
to fill the two halves of the input vector, however this has the effect
of introducing an unnecessary dependency on the value of the vector from
the previous loop iteration.
This doesn't really seem to affect little core performance since these
cores never execute enough work concurrently to hit the bottleneck,
however we can improve performance on mid and big cores quite a bit by
using LDR instead of LD1 to load the low lane, zeroing the upper portion
of the vector rather than keeping the previous value.

Recent versions of Clang always define these TARGET_ macros (to 0 or 1
as appropriate) for Apple targets.
https://chromium-review.googlesource.com/c/libyuv/libyuv/+/5249072
made the code correctly check the *value* of the macro rather than
whether it was defined or not.
However, the code was still broken when actually targeting the iOS
simulator (where the macro is now 1).
It seems the use of this macro was just incorrect, and the code only
worked since it was never defined at all.
The original use of the macro in this file was added in
2c8108e6c2
but it 's not quite clear to me why.
All other uses have subsequently been removed, e.g. in
6a1d01220a
this removes the last instance, and should fix the iOS simulator builds.

The macro may be defined to 0; the code needs to check the value, not
just whether it's defined.
Recent Clang versions will define all Apple "target OS" macros by
default (see bug).

Root cause:
Because InterpolateRow_RVV doesn't setup rounding mode to round-to-nearest-up when y1_fraction == 128.
The rounding mode register is set to round-down in ARGBAttenuateRow_RVV.
It cause InterpolateRow_RVV(y1_fraction == 128) runs on round-down mode.
Running on round-down mode make output result differs from round-to-nearest-up mode.
Solved by: ensure to use correct rounding mode in InterpolateRow_RVV.
Also, removing unnecessary rounding mode setup in ARGBAttenuateRow_RVV.

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.

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.

Which is: 536870912
[ FAILED ] LibYUVBaseTest.TestLinuxRVV (17 ms)
Reason:
The root cause is "\n" may be contained in the ext variable.
The last of extension substring contains "\n".
For instance, test case riscv64_rvv_zvfh.txt, the last substring is "zvfh\n" instead of "zvfh".
Solved this failure by removing "\n" which is at the end of line.
NOTE: We avoid using strstr() to solve the problem here.
Becasue using strstr() will violate the parsing rule, if future extension contains "zvfh"(e.g zvfhxxx).

This function reads 2 byte values and writes the 2nd byte to the destination.
It turns out this is useful for P010ToNV12 as well, so adding the planar function allows a high level to call this.

When doing 90 or 270 degrees rotation we need to do a rotate&scale of the UV planes, as there are no helper optimized functions to do this, we use the Y plane as temporal memory and perform each of the transforms independently:
First U plane is rotated, putting the result in the Y plane. After the rotation, the output has double the samples horizontally and half the samples vertically, so it is scaled into the final U plane. Same process is done with the V plane.
Last the Y plane that can be just rotated without scaling.
It would be great to have an optimized version for this, but maybe this is helpfull for triggering the discussions.

These functions convert between planar and interleaved ARGB,
optionally fill 255 to alpha / discard alpha.
This can help handle YUV(A) with Identity matrix, which is
basically planar ARGB.

This includes:
- fixing a handrolled raw exec-based DEPS parser that was failing
to parse Str, similar to crbug.com/1106435.
- rolling chromium forward by nearly a year. (The last roll that
landed was crrev.com/c/1797295). This required a bunch of changes in
order to be able to successfully sync, run gn, and compile:
- switching the mirrors for three repositories to match chromium,
which switched in crrev.com/c/2062580.
- making libyuv write an empty gclient_args file
- adding a few build_override gn arguments
- adding nasm as a deps entry, as it's now required by libjpeg_turbo
- android:
- adding jdk, libunwindstack, and turbine
- rolling the android sdk
- rolling bazel and r8
- rolling the cipd packages managed by third_party/android_deps
- adding six and requests to .vpython for the test runner
- switching to memcpy in a few places to avoid SIGBUS errors on
arm due to unaligned reads
- linux:
- checking out instrumented libraries for msan (including adding
depot_tools to deps for the hook)
- mac:
- adding mac_xcode_version to gclient_gn_args
- win:
- limit mac_toolchain to checkout_mac
