The "age" of mmx has been brought up for a while now, but latest intel CPUs
still support it, so I agree it's fine for now.

OK.

[FFmpeg-devel] [PATCH 0/4] More H.264 assembly (the sequel) [version 2]

[James Darnley]

Fixed the problem Michael highlighted.  Dropped the intra functions until it
becomes clear why their performance is unexpected. Updated the benchmarks with
results from a Nehalem and used (slightly) more accurate data.

Regarding the age of MMX:  I have written it so unless someone tells me to
remove it I will keep the code.  However, I will probably not write any more
going forward.
