[FFmpeg-devel] [PATCH] Add check for Athlon64 and similar AMD processors with slow SSE2.

This was ported from x264 so we need permission to relicense from
Loren, Jason, or whoever added this particular check in x264.

Once this is added, I can go through libavcodec/x86 and test various
SSE2 functions on my Athlon64 to check if they're faster with other
versions.  We also have a couple functions now that are hackishly
handled by disabling SSE2 for all AMD processors by checking the
3DNow flag.  Those are the ones I'll test first.
