  x86: AVX2 high bit-depth pixel_sad
  
  Also use loops instead of duplicating code; reduces code size by ~10kB with
  negligible effect on performance.

  Also reduce the number of xmm registers used by mc_copy_* to avoid
  saving and restoring xmm6 and xmm7 on 64-bit Windows.

  Also rewrite the entire function to be faster and drop the AVX version which is no longer useful.
