problem where it inline the map insertion call too aggressively. Before this
change it was producing a frame size of 24k for Select_store(), now it's down

This is a bugfix for SelectNodeTo. In certain situations, we could be
...
selecting a node and use a mix of getTargetNode() and SelectNodeTo. Because
SelectNodeTo didn't check the CSE maps for a preexisting node and didn't insert
its result into the CSE maps, we would sometimes miss a CSE opportunity.
This is extremely rare, but worth fixing for completeness.
