Found by ubsan: if rhs is nullptr, then we fed a nullptr as the second
argument of memcmp(), which is UB.
Fix by catching an empty rhs before we reach that line.
Amends e52d50a03da29e2dddaee551e4409f28c7ed56f2 (which, despite
pick-to's to the contrary, never made it into 6.2 or 5.15).
Change b977ae371a753a82e1d0bb32c5b62099da663721 fixed this for
UTF-8/UTF-8 comparison from 6.5 on, but 6.4 ad 6.3 remain vulnerable
there, but they're closed, so can't be fixed anymore.
Pick-to: 6.7 6.5
