Temporarily go back to using const Node* instead of RawPtr<const Node> for the non-oilpan NodeToDestinationInsertionPoints map.

This is to fix the current non-oilpan regression in this code. I am
actively working on a real fix teaching the HashMap to treat RawPtr
as actual raw pointers. As soon as I have that fix I will move this
back to using RawPtr again and avoid the ifdef.
