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.
