Default gcwsieve 1.0.14

The main loop for SSE2 and x86-64 machines is now 100% assembly instead of a mixture of C and inline assembly, and tries to read memory in a more predictable way.

The 32-bit executable runs about 15% faster on my P4, and the 64-bit executable runs about 60% faster on my C2D. (64-bit is now almost twice as fast as 32-bit on the C2D).
