Make the wchar_t promotion test consistent across different hosts by specifying a target triple.

This test behavior differs depending (at least) on whether
sizeof(wchar_t) == sizeof(int) or not.

When they are equal, the first redeclaration will fail because decltype(+L'x')
is unsigned int instead of the expected int. This occurs on ARM.
