Frank Barchard 63b56324de [libyuv] Replace AVX-512 _Any wrappers with k-mask tail handling ... Replace stack-buffer memcpy _Any wrappers with native AVX-512 k-mask tail handling across 8 AVX-512 row kernels (unlocking composite RGBToUVMatrixRow_AVX512BW as well) and remove IS_ALIGNED dispatch constraints: - MirrorSplitUVRow_AVX512BW: Masked 16-bit load (vmovdqu16 %{k1%}%{z%}), dynamic reverse index (vpsubw + vpermw via kMirrorUVPermute_AVX512), and vpmovwb %{k1%} U/V stores; unlocks unaligned SplitRotateUV180. - ARGBToUVMatrixRow_AVX512BW: Fix MASK=63 vs 32-pixel loop bug; zero-load tail dwords per row, duplicate odd final pixel via knotw + vpshufd, and store masked U/V bytes. - I422ToARGBRow_AVX512BW & I422ToAR30Row_AVX512BW: Add masked Y/U/V loads (READYUV422_MASK_AVX512BW) and masked ARGB/AR30 stores. - CopyRow_AVX512BW: Add 64-byte full vector step + bzhi masked tail. - BlendPlaneRow_AVX512BW, ARGBShuffleRow_AVX512BW, RGBToARGBRow_AVX512BW (RAWToARGBRow_AVX512BW / RGB24ToARGBRow_AVX512BW): Masked loads and stores in both row_gcc.cc inline assembly and row_win.cc intrinsics. Reduces x86-64 binary .text size by 2,592 bytes with 0 bytes added to .rodata.
