70ac57b95b Change various CPU_ARM defines to _ARM_ASSEM_ to be more consistent with the rest of Tremor.

9e45b27e08 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).

87ecc7020e 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

7b24423180 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)

95cf600b6c Macros should be ALL CAPS, so rename (un)likely() to (UN)LIKELY()

1284c127f8 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
