[mpeg2-dev] [PATCH] SSE2 idct optimizations

[Diego B. <di...@bi...>]

This patch supercedes previous incarnations sent in by Petri and Lionel.
It takes the idct part from their patches along with minor cleanups and
should be easier to review/verify.

The motion compensation part contained in Petri's/Lionel's patch is not
yet proven to give any sort of improvement, benchmarks would be needed.
