Enable compilation of improved x86 code generation with MSVC

Browse Source 
Now that we know the compiler flags for asking MSVC to produce SSE2 code
properly as well as AVX code (technically, just VEX-prefixed SSE2), we
may as well use it.

The SSE2 code generation is enabled by this commit. The AVX one
requires a change to configure to detect the support in the compiler.
