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.

integral promotions to both its underlying type and to its underlying type's
promoted type. This matters now that boolean conversions aren't permitted in
converted constant expressions (a la DR1407): an enumerator with a fixed
underlying type of bool still can be.
