Don't fall back to raise(SIGTRAP) on Windows

Browse Source 
When targeting mingw on architectures other than x86, the earlier cases
don't apply, and the final fallback, raise(SIGTRAP) isn't usable there.

GCC and Clang both support __builtin_trap(), so in case we have no
other alternatives, and are on windows (where raise() isn't available),
we can resort to this.
