Summary: When inserting a new Def, and inserting Phis in the IDF when needed, also mark the already existing Phis in the IDF as non-optimized, since these may need fixing as well. In the test attached, there is a Phi in the IDF that happens to be trivial, and is wrongfully removed by the call to getLastDef that follows. This is a valid situation and the existing IDF Phis need to marked as "may need fixing" as well. Resolves PR43044.
