Fix DROP OPERATOR to reset oprcom/oprnegate links to the dropped operator.
This avoids leaving dangling links in pg_operator; which while fairly
harmless are also unsightly.
While we're at it, simplify OperatorUpd, which went through
heap_modify_tuple for no very good reason considering it had already made
a tuple copy it could just scribble on.
