83d3dcfd88 Coldfire: Assembler optimised memcpy(), 2.4x...10x (avg. 6.8x) as fast as the C version when copying large blocks within SDRAM.

d8ad74de74 SH1 memcpy(): Slightly changed loop concept: saved 4 bytes, and the long+1 case is now as fast as the long+3 case.

c082bc42a2 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).

0310f16005 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).
