Hi all

This is version 2 of the following patch:

This patch implements several mpegaudio optimizations for SH4 FPU-enabled 
SoCs. Verified to provide more than 40% acceleration, when decoding a 
128kbps stereo mp3 audio file to /dev/null.

Changes listed in the patch header, thanks to all who commented!
