[Bug c++/41201] #pragma GCC target ("sse2") doesn't alter __SSE2__ in C++ (as it does in C)

FWIW, it seems that MSVC is perfectly happy to compile code with intrinsics
inside a file which doesn't have any special flags.  It would be awesome if
there were some way to do the same with GCC, even if it involves #pragma
hackery.  The current limitation makes using intrinsics pretty painful, as it
requires a separate file for each targeted instruction set.
