msvcrt: Introduce _setfp helper to access floating point status and control
words.

The problem lies in "unsigned int CDECL _clearfp(void)", which calls "_setfp".
This in turn breaks on the line

__asm__ __volatile__( "fldenv %0" : : "m" (fenv) : "st", "st(1)",
                "st(2)", "st(3)", "st(4)", "st(5)", "st(6)", "st(7)" );

Since I'm not sure what's going on here, mind taking a look?
