Zachary Turner afdff425d7 Make UTF8->UTF16 conversion null terminate output on empty input.

Zachary Turner 02991af057 Have the UTF conversion wrappers append a null terminator. 
This is especially useful for the UTF8 -> UTF16 direction, since
there is no equivalent of llvm::SmallString<> for wide characters.
This means that anyone who wants a null terminated string is forced
to manually push and pop their own null terminator.

Reid Kleckner d8cb6b00c5 Add a UTF8 to UTF16 conversion wrapper for use in the pdb dumper 
This can also be used instead of the WindowsSupport.h ConvertUTF8ToUTF16
helpers, but that will require massaging some character types. The
Windows support routines want wchar_t output, but wchar_t is often 32
bits on non-Windows OSs.
