Coldfire: Assembler optimised memcpy(), 2.4x...10x (avg. 6.8x) as fast as the C version when copying large blocks within SDRAM.

SH1 memcpy(): Slightly changed loop concept: saved 4 bytes, and the long+1 case is now as fast as the long+3 case.

Further optimised SH1 memcpy(): Lower latency for very small blocks, faster large block copying for odd destination alignment (+27% for long+1, +33% for long+3).

Added CPU_COLDFIRE define - one step closer to iAudio-port

Revived C implementations of memcpy() and memset() for platforms without asm optimized versions (gmini), replacing the intermediate strings.c. Moved the asm optimized versions 'out of the way' for the implicit 'make' rules by renaming them to *_a.S (for assembler/alternative).
