I'm sorry to say, I can't test it. I tried crippling ffmpeg into
thinking my opteron doesn't have sse, but I think I missed something.
As far as I can tell, it should work. It's a lot better than what I
was thinking of.

Off-topic: was imdct_calc put in the FFTContext struct to save a call
to mm_support() ?
