I've ported some of the ASM code from the WMA codec to libfaad with help from ammicon. This gives me a minor speedup on PP (saves ~1MHz). I'm curious to see how much it saves on Coldfire (and if it sounds alright).

Fixed a mistake that prevented compiling on coldfire (thanks n1s) and another that caused subtle glitching.
