Frank Barchard c15967905d [libyuv] Implement 8, 16, and 32-bit transpose using x86 ACEv1 
Add kCpuHasACEV1 detection to CpuId using CPUID leaves 7.1, 0x1D.2,
and 0x24.1 along with XCR0 state validation (0x001600e6). Add
CLANG_HAS_ACEV1, GCC_HAS_ACEV1, and LIBYUV_TARGET_ACEV1 macros for
64-bit x86 builds on Clang >= 11 and GCC >= 11.

Implement TransposeWxH_ACEV1, TransposeUVWxH_ACEV1,
TransposeWxH_16_ACEV1, and TransposeWxH_32_ACEV1 in rotate_gcc.cc
using Palette 2 16x16 dword tiles (ldtilecfg, tilemovcol, tilemovrow,
and tilerelease) with k-register tail masking for arbitrary widths and
heights.

Bug: none
Test: sde64 -future-ag -- ./libyuv_unittest --gtest_filter=*Transpose*

README.md

libyuv is an open source project that includes YUV scaling and conversion functionality.

  • Scale YUV to prepare content for compression, with point, bilinear or box filter.
  • Convert to YUV from webcam formats for compression.
  • Convert to RGB formats for rendering/effects.
  • Rotate by 90/180/270 degrees to adjust for mobile devices in portrait mode.
  • Optimized for SSSE3/AVX2 on x86/x64.
  • Optimized for Neon/SVE2/SME on Arm.
  • Optimized for MSA on Mips.
  • Optimized for RVV on RISC-V.
