It's possible to easily implement `reference_constructs_from_temporary` in the library, but the converts one is far more tricky because `__reference_binds_to_temporary` only cares about construction. I don't know if GCC implements it (I thought it did, but I can't find the commit in a trivial Google search), but I did learn that libstdc++ has a guard for this name.
