Ari Koivula 42295d3cb9 Pass preprocessor defines for supported intrinsics in VS2010 explicitly.
- _M_IX86_FP defines whether VS should generate code using SSE or SSE2
  instructions. It isn't correct to use it to check whether optional runtime
  optimizations should be compiled in. It's also not defined at all in 64-bit
  mode.

- So let's just keep it simple and give a list of everything that is supported
  as release optimizations. It's not clear from the documentation if all of
  these are really supported. It just list a bunch of intrinsics from these
  that are.

Ari Koivula bd7e021742 Modify strategyselector to work with VS2010.
- VS doesn't have snprintf.

- VS doesn't support GCC attributes.

- Add defines for __SSE__ and __SSE2__ on VS.
