Ted Kremenek ec2dc73e86 [-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.
