wchar_t can be signed (thus hasSignedIntegerRepresentation() returns
true), but it doesn't have an unsigned type, which would lead to a crash
when trying to get it.
With this fix, we special-case WideChar types in the pointer assignment
code.

Fix string concatenation to treat escapes in concatenated strings that
are wide because of other string chunks to process the escapes as wide
themselves. Before we would warn about and miscompile the attached testcase.
This fixes rdar://8040728 - miscompile + warning: hex escape sequence out of range

- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).
