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.
