The PR adds a way to convert a parent pointer tree to a full tree, which allows for tree traversal and quick reverse lookups (call site -> stack trace identifiers). This lightweight operation is instrumental for implementing #3219, #3384, #3220, and #2729. As of now, it is not used anywhere, but I'm afraid of forgetting the algorithm, so I'm adding it to the codebase.
