This has an SSE2 IDCT (which looks like it was just transcribed from
x86-64 asm, so no macros or useful variable names). If it works well
with half the xmm registers, it might be nice.

I don't think AAN is the best IDCT algorithm, though - maybe it would
be better to port ppc/idct_altivec.c?

I don't think this library is really useful without CABAC, but the
SSE2 deblocking might be helpful. The rest probably isn't worth
anything.
