ec8f72bf20 Use roundss/roundsd when available for Ceil/Floor/Trunc/Nearest (#931) 
Don't tie the preexisting SIMD ISA predicates to the shared
enable_simd setting but make new ones instead.

b4ef90cfcd Remove SSE2 setting for x86 
In talking to @sunfishcode, he preferred to avoid the confusion of more ISA predicates by eliminating SSE2. SSE2 was released with the Pentium 4 in 2000 so it is unlikely that current CPUs would have SIMD enabled and not have this feature. I tried to note the SSE2-specific instructions with comments in the code.
