When migrating, we'll need to change some null-aware property accesses and method calls to non-null-aware (due to the fact that the receiver is non-nullable, or due to the new `?.` shortcut rules), so when migration re-resolves, it will need to be able to override resolution's determination of whether a given property access or method call is null-aware.
