After better testing I have decided to only submit these two functions.  The
others did not provide a speedup better than the deviation in testing.  Those
patches remain in the list archive should someone wish to try them.

James Darnley (5):
  avcodec/h264: change RETs into REP_RETs where appropriate
  avcodec/h264: change some labels to be macro-local
  avcodec/h264: use some 3 operand forms
  avcodec/h264: add avx 8-bit h264_idct_add
  avcodec/h264: add avx 8-bit h264_idct_dc_add
