George Steed 772bddaed7 Add missing memory/cc clobbers to AArch64 Neon kernels 
There are a few functions in source/scale_neon64.cc which write memory
and set condition flags despite not declaring this in the asm clobber
list, so add the missing clobbers.

Also move a couple of memory/cc clobbers to the start of the clobber
list to match other kernels.

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.
