CentOS 7 comes with an outdated libstdc++ version. In that version, `std::basic_string` has a `mutable` member, which makes all of `basic_string`'s member functions mutating in Swift. This prevents us from calling `size()` or `empty()` on an immutable value of `std.string`. rdar://91548568 rdar://91670704
