Reviewers: Vyacheslav Egorov, Description: Implement explicit back pointers in transition tree.
This makes back pointers in the map transition tree explicit by having accurate back pointers throughout the lifetime of maps instead of establishing and destroying back pointers before and after each marking phase. This is a prerequisite for being able to clear map transitions during incremental marking.
