  x86: SSSE3 LUT-based faster coeff_level_run
  
  ~2x faster coeff_level_run.
  Faster CAVLC encoding: {1%,2%,7%} overall with {superfast,medium,slower}.
  Uses the same pshufb LUT abuse trick as in the previous ads_mvs patch.

• x86 : SSSE3 ads_mvs

  20 mars 2013, par Jason Garrett-Glaser

  x86: SSSE3 ads_mvs
  
  ~55% faster ads in benchasm, ~15-30% in real encoding.
  ~4% faster "placebo" preset overall.
