Handle rewriting multi-return instrs
Summary:
When performing a rewrite if the instruction being rewritten is multi-return and is followed by Select instructions then the rewriter needs to know how to route the Select InstrIds.
This change
(a) detects if the Selects were not re-routed properly.
(b) automatically reroutes them in simple cases.
(c) allows more complex cases.
