16af162cf9 [libyuv] Optimize RotatePlane_16 SIMD and compact 32-bit transposes 
Implement SIMD 16-bit plane rotation (TransposePlane_16,
RotatePlane90_16, RotatePlane180_16, RotatePlane270_16) used by
I010Rotate, I210Rotate, and I410Rotate, keeping tile sizes compact
with full-register writes and zero cross-lane shuffles:
- AVX2: 8x16 tile in ymm0..ymm15 with _Any tail (low-end x86 SIMD)
- AVX-512BW: 8x32 tile in zmm0..zmm15 with k1/k2 right/bottom masks
- NEON (ARM64/ARM32): 8x16 tile in v0..v23 / q0..q11 with _Any tail
- SME: 8xVL tile using ZA16 horizontal/vertical array slices
- RVV: 8xVL tile using widening unpacks with hardware vl tail
- WASM SIMD: 8x8 tile in v128 with _Any tail

Also update 32-bit ARGBRotate x86 transposes to compact vertical
in-lane tiles with full-register writes and zero cross-lane shuffles:
- TransposeWxH_32_AVX2: 4x8 tile in ymm0..ymm7 with vpmaskmovd tails
- TransposeWxH_32_AVX512BW: 4x16 tile in zmm0..zmm7 with k1/k2 tails

Add RotatePlane16_SplitMergeUV_Opt and RotatePlane16_SplitMergeUV_Odd
unit tests comparing 16-bit rotation against SplitUVPlane +
RotatePlane + MergeUVPlane across 0/90/180/270 degrees.

eeb06a6451 [libyuv] Optimize ARGBRotate for Intel SSE2, AVX2, and AVX-512 
Optimize 32-bit ARGBRotate (0, 90, 180, 270) across Intel x86/x64
architectures (SSE2, AVX2, AVX512BW), with matching kernels for ARM
(NEON, SVE2, SME), WASM, LoongArch (LSX, LASX), and RISC-V (RVV):

- Replace column-by-column ScaleARGBRowDownEven gather loops in
  ARGBTranspose (90/270) with full-plane horizontal tile transposes:
  - AVX512BW (TransposeWxH_32_AVX512BW / TransposeNx4_32_AVX512BW):
    Transpose 16x16 blocks across zmm0..zmm31 using 4-stage
    vpunpckldq/hdq, vpunpcklqdq/hqdq, and vshufi32x4 butterflies with
    k-masked right and bottom tails, eliminating Any wrappers and scalar
    C edge fallbacks.
  - AVX2 (TransposeWxH_32_AVX2 / TransposeNx4_32_AVX2):
    Transpose 8x8 blocks across ymm0..ymm15 using vpunpck* and
    vperm2i128 with vpmaskmovd masked tails.
  - SSE2 (Transpose4x4_32_SSE2 / Transpose4x4_32_Any_SSE2):
    Transpose 4x4 blocks in xmm registers.
- Implement ARGBRotate180 directly via ARGBMirror with negative height,
  avoiding intermediate row buffer allocations and extra copies.
- Implement ARGBRotate0 via ARGBCopy.

Speedup vs Before (1275x1650, US Letter 150 DPI, 1000 iterations):
CPU                  | 0 deg   | 90 deg  | 180 deg | 270 deg
---------------------|---------|---------|---------|--------
Intel Ice Lake       | 1.02x   | 1.34x   | 1.18x   | 1.33x
Intel Skylake-X      | 1.02x   | 1.20x   | 1.07x   | 1.13x
Intel Emerald Rapids | 1.01x   | 1.07x   | 1.00x   | 1.07x
Intel AVX-512 vs C   | 1.00x   | 2.67x   | 2.41x   | 2.63x

0c781f87b8 [libyuv] Keep LIBYUV_API in basic_types.h and remove legacy types and bool macros 
Reduces include/libyuv/basic_types.h to only define LIBYUV_API.
Directly includes <stdint.h> and <stddef.h> where needed in public
headers.
Replaces LIBYUV_BOOL, LIBYUV_FALSE, and LIBYUV_TRUE with C++ bool,
true, and false in C++ code (MJpegDecoder, unit tests) and int (0, 1)
for C API functions.
Updates documentation and unit tests.

ebe6fef903 Fix integer overflow in multiplications of stride 
Audit all occurrences of "stride *" in the libyuv source tree. Ensure
that these multiplications are performed in the ptrdiff_t type.

For functions not declared in a public header (such as static
functions), prefer to declare the stride parameters (typically named
src_stride and dst_stride) and related stride local variables as
ptrdiff_t. If this is not possible, add ptrdiff_t casts to the stride
parameters in multiplications. If intptr_t or int64_t casts were used,
change them to ptrdiff_t casts.

cf101116c9 Remove initialize to zero on output variables for inline. 
Inline that uses temporary variables is currently initializing them
to 0 and passing in as output "+r".
This CL replaces the output constraint to "=&r" for most meaning an
output with early write (before inputs).  This allows the initialize
to zero step to be removed, saving 1 instruction.

f7e74a1a6f Move neon rotate code from straight assembly to inline. 
Allow assemblers with a slightly different syntax to use
the optimized neon routines.

Removed extra constraints on the calling of the optimized
routines.  All neon routines can load unaligned and handle
odd widths.

Align allocated buffers in rotate_test.cc

Add neon rotate file to gyp file for arm targets.
