CABAC trellis opts part 4: x86_64 asm
Another 20% faster.
18k->12k codesize.

This patch series may have a large impact on encoding speed.
For example, 24% faster at --preset slower --crf 23 with 720p parkjoy.
Overall speed increase is proportional to the cost of trellis (which is proportional to bitrate, and much more with --trellis 2).
