Driver: default to `unsigned int` `wchar_t` for ARM AAPCS and AAPCS64 mandate that `wchar_t` with `-fno-short-wchar` is an `unsigned int` rather than a `signed int`. Ensure that the driver does not flip the signedness of `wchar_t` for those targets. Add additional tests to ensure that this does not regress. llvm-svn: 316858
