enable sincos optimization on mingw-w64
The sincos transformation does not take place on all platforms,
because the libc_has_function target hook disables it by default.
Current mingw-w64's math library supports sincos, sincosl and sincosf,
in 32- and 64-bit modes. I suppose this has been this way for long.
This patch enables the sincos optimization on this platform.
for gcc/ChangeLog
* config/i386/mingw-w64.h (TARGET_LIBC_HAS_FUNCTION): Enable
sincos optimization.
