[-Wunreachable-code] don't warn about dead 'return <string literal>' dominated by a 'noreturn' call, where literal becomes an std::string.
I have mixed feelings about this one. It's used all over the codebase,
and is analogous to the current heuristic for ordinary C string literals.
This requires some ad hoc pattern matching of the AST. While the
test case mirrors what we see std::string in libc++, it's not really
testing the libc++ headers.
