Summary: When inserting a Def, the current algorithm is walking edges backward and inserting new Phis where needed. There may be additional Phis needed in the IDF of the newly inserted Def and Phis. Adding Phis in the IDF of the Def was added ina previous patch, but we may also need other Phis in the IDF of the newly added Phis.
