Frank Barchard bcb69c8eb6 [libyuv] Remove all x86 SSE optimizations 
Removed all SSE functions, macros, dispatching logic, and related
unit tests across the repository to reduce code size and complexity.
Left cpuid detection intact. Supported architectures like AVX2, NEON,
SVE, etc. are unaffected.

Bug: None
Test: Build and run libyuv_unittest

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.
