Have LookupFuncName accept NULL argtypes for 0 args

Prior to this change, it requires to be passed a valid pointer just to
be able to pass it to a zero-byte memcmp, per 0a52d378b03b.  Given the
strange resulting code in callsites, it seems better to test for the
case specifically and remove the requirement.
