      Chroma weighted prediction · f92aa4ec
      Fiona Glaser authored
      Like luma weighted prediction, dramatically improves compression in fades.
      Up to 4-8db chroma PSNR gain in extreme cases (short, perfect fade-outs).
      On actual videos, helps up to ~1% overall.
      One example video with a decent number of fades (ef OP): 0.8% bitrate reduction overall, 7% bitrate reduction just counting chroma.
      Fixes a lot of artifacts in fades at lower bitrates.
      Original patch by Dylan Yudaken <dyudaken@gmail.com>.

      Overall speed change from these 6 asm patches: ~4.4x.
      But there's still tons more asm to do -- patches welcome!
      Breakdown from this patch:
      ~13x faster SAD than C.
      ~11.5x faster SATD than C (only MMX done).
      ~18.5x faster SA8D than C.
      ~19.2x faster hadamard_ac than C.
      ~8.3x faster SSD than C.
      ~12.4x faster VAR than C.
      ~3-4.2x faster intra SAD than C.
      ~7.9x faster intra SATD than C.
