Assembler optimised bitreverse for ARM, again a little bit faster and smaller. * Separated 'x' and 'ret' gives gcc a bit more freedom regarding register allocation (except on coldfire where it doesn't matter).

Improved bitrev with approach suggested by Jens Arnold, gives 0.5%-1% speedup for tremor decoding on sansa c200 (PP) and a tiny speedup on coldfire as well

Use optimised byteswap function in bitrev for a tiny speedup on coldfire and pp and about 1-2% speedup on gigabeat s (due to the armv6 rev instruction)

Introduce likely() and unlikely() macros, use to give gcc hints about which branch is likely to be taken in a conditional, use them in the midi player for a small speedup, use instead of similar EXPECT macros in tremor and use in mpegplayer
