Thiago Macieira b4525b3407 Add configure-time checking for the SSE and AVX features on Windows ... Modify configure.exe to run some configure-time tests and check if the SSE and AVX compiler features are supported. The tests themselves required a bit of changes to compile with MSVC. The include in sse4_2.cpp was wrong. And for whatever reason, it didn't like the volatile variables, which GCC, Clang and ICC have been happy with. This should produce no effect in compilation, though: even dead code must be syntactically correct. We're not running the output.
