FS#11309 - Minor asm changes to codecs
This patch adds some minor changes to libmad, libmpc and libatrac. It incorporates FS#11235 (libmad optimization for ARM9).
Speed up on PP502x for mpc and atrac3 is ~0.05-0.1 MHz – not much, but reproducible slightly faster. The speed of libmad on PP502x is same as svn, but for >=ARM9 it was reported to be ~0.2 MHz faster.

Speed-up is only minor on PP502x , but
speed was reported to be minor slower on
ARM9. So, drop this change.

New version which uses appropriate clobber lists in libmad's asm routines. Also do some reformatting.
