Various speedups: (1) Put actual decoding functions into IRAM on PP5002. (2) Put the insane filter buffer into IRAM on coldfire and PP502x (just for completeness, as long as there's no better use). (3) Use the ARMv6 'ssat' instruction for saturation on Gigabeat S.

ARM assembler predictor decoding function. This increases my -c1000 test track from around 94% realtime on an ipod to around 104% realtime, but yields only a tiny speedup (453% to 455%) on the Gigabeat. Including this optimisation, total decoding time for my 245.70s -c1000 test track on an ipod is 236.06s, with the predictor decoding taking 51.40s of that time - meaning the predictor decoding is only about 22% of the total decoding time.
