George Steed e1a93c79fc [AArch64] Fix rotate by odd sizes 
The existing disabled gtest rotate tests fail because the existing "any"
kernels always assume we are processing height=8 rows at a time. This
was recently changed to 16 on AArch64 which triggered this bug.

To fix this, amend the TANY macro to explicitly specify the fallback
kernel, such that we can use the height=16 kernel to match the SIMD
optimized version where necessary. Also change other architecture
versions to match.

Bug: b/352351302

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 on Arm.
  • Optimized for MSA on Mips.
  • Optimized for RVV on RISC-V.
