--- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
GCC is correct:

    llvm::StringRef GetHelp() { return (m_help.empty() ? "" : m_help); }

has a std::string temp for "" because the conversion to std::string in the ?:.
And then StringRef::StringRef does:
     /// Construct a string ref from an std::string.
     /*implicit*/ StringRef(const std::string &Str)
       : Data(Str.data()), Length(Str.length()) {}


So GCC is correct.
