Here's a patch for opt that makes it take an -mtriple option, and a
revised patch for pr12559 that tests that (float)floor, (float)ceil,
and (float)sqrt still optimize to single-precision libcalls for mingw
and win64 targets. (There doesn't appear to be such an optimization
implemented yet for other math libcalls available on Windows.)
