Early we used tcmalloc heap dumps for check what classes have to be instrumented first.
We instrumented a lot of classes and it became difficult to use heap dumps for this task.
We need a way to see the classes that aren't instrumented yet or their objects were not reached during snapshot.
We could use heap dump but need to mix tcmalloc data with the data about already counted objects.
