Why not just use a std::string then. Both std::string and StringRef will have
similar compare times.

No. If we are talking about making the code safer, I would rather go with
something that can guarantee safety. The StringRef has the possibility of going
wrong if someone uses a local string. So unless we can guarantee it I don't see
a reason to change.
