Ted Kremenek f3c93bb61b [-Wunreachable-code] Simplify and broad -Wunreachable-code-return, including nontrivial returns. ...

The exception is return statements that include control-flow,
which are clearly doing something "interesting".

99% of the cases I examined for -Wunreachable-code that fired
on return statements were not interesting enough to warrant
being in -Wunreachable-code by default.  Thus the move to
include them in -Wunreachable-code-return.

This simplifies a bunch of logic, including removing the ad hoc
logic to look for std::string literals.
