This series fixes PR c++/21323, a bug report that shows that GDB
thinks C++11's char16_t and char32_t built-in types are signed, while
the standard clearly says they're unsigned.
While working on it, I noticed that GDB isn't aware that wchar_t is a
built-in type in C++ either (and it was already the case in C++98).
The second patch fixes that.
Tested on x86_64 Fedora 23.
New in v2:
- Make the tests a bit more lax when testing C/C++98, WRT to the
underlying type of char16_t/char32_t - accept any of unsigned
long/short/int.
- Go through all ports and override wchar_t size/sign appropriately.
