George Steed b7d97d5f3f [AArch64] Fix compilation due to incorrect register constraint 
The y0_fraction and y1_fraction variables in InterpolateRow_NEON were
marked as modified by the inline-asm block, however
5eea7812826c551559fdcd4a6988fcf1fbe341f6 marked these variables as
`const` which caused both LLVM and GCC to emit errors about modification
of const variables.

There is no need for these variables to be modified in the loop since
they are read-only, so simply update the inline asm block constraints to
match.

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.
