Based on Philipp Hancke's AVX2 column kernel for ScaleUVBox at 3x (https://crrev.com/c/8427347). Add ScaleUVAddCols3 for exact 3x horizontal downscaling (dx == 0x30000 and boxheight <= 85) in ScaleUVBox, plus ScaleAddRow_AVX512BW and ScaleAddRow_WASMSIMD dispatch, and port 3x/box scaling kernels in scale_win.cc to 32/64-bit C++ intrinsics matching scale_gcc.cc: - ScaleUVAddCols3_C (portable C) - ScaleUVAddCols3_AVX2 and ScaleUVAddCols3_Any_AVX2 (scale_gcc.cc and scale_win.cc) - ScaleUVAddCols3_AVX512VBMI (scale_gcc.cc and scale_win.cc) - ScaleAddRow_SSE2, ScaleAddRow_AVX2, ScaleAddRow_AVX512BW, ScaleAddCols1_AVX512BW, ScaleAddCols2_AVX512BW, ScaleRowDown38_SSSE3, ScaleRowDown38_2_Box_SSSE3, and ScaleRowDown38_3_Box_SSSE3 in scale_win.cc for 32/64-bit Visual C and LIBYUV_ENABLE_ROWWIN - ScaleUVAddCols3_NEON (32-bit ARM and 64-bit AArch64) and ScaleUVAddCols3_Any_NEON - ScaleUVAddCols3_SME (ARMv9 Streaming SVE with whilelt predicate tail) - ScaleUVAddCols3_RVV (RISC-V Vector vlseg3e32.v inline asm) - ScaleUVAddCols3_LSX and ScaleUVAddCols3_Any_LSX (LoongArch LSX) - ScaleAddRow_WASMSIMD, ScaleAddRow_Any_WASMSIMD, ScaleUVAddCols3_WASMSIMD, and ScaleUVAddCols3_Any_WASMSIMD - ScaleUVAddCols3_HVX (Hexagon HVX vrdelta + vmpy_VuhRuh) Co-authored-by: Philipp Hancke <philipp.hancke@googlemail.com> Bug: libyuv:564129034 R=rrwinterton@gmail.com Change-Id: Ib9e14f3efcb097842c3d0e9fc9b473b6e2f81871 Reviewed-on: https://chromium-review.googlesource.com/c/libyuv/libyuv/+/8596436 Reviewed-by: richard winterton <rrwinterton@gmail.com>
