Every time replace_in_map() is called, the pair of nodes passed to replace_in_map is pushed on a list that the current map carries. When control flow paths merge, the lists for each of the control flow path’s maps are also merged. When parsing exits a method to return to a caller, the replaced nodes on the exit path are used to update the caller's map. This change also propagates replaced nodes after late inlining.
