Return orig_emit from S_regclass() when ret_invlist is true.

The return value isn't used (yet). Previously the code was returning END,
which is a macro for the regnode number for "End of program" which happens to
be 0. It happens that 0 is valid C for a NULL pointer, but using it in this
way makes the intent unclear. Not only is orig_emit a valid type, it's
semantically the correct thing to return, as it's most recently added node.
