Escape analysis uses Node.Opt to map nodes to their "location", so that other references to the same node use the same location again. But in the current implementation of escape analysis, we never need to refer back to a node's location except for named nodes (since other nodes are anonymous, and have no way to be referenced). This CL moves Opt from Node down to Name, turns it into a directly accessed field, and cleans up escape analysis to avoid setting Opt on non-named expressions. One nit: in walkCheckPtrArithmetic, we were abusing Opt as a way to detect/prevent loops. This CL adds a CheckPtr bit flag instead. Passes toolstash -cmp.
