When you run the elidable-new-object-roflcopter test, you'll see that there are many repeated PutStructureHints and PutByOffsetHints. These are because we handle already-sunken allocations from previous fixpoint iterations inside the code for handling those allocations we are sinking on *this* fixpoint iteration. This is a mostly benign bug; its main effect is that if the phase does many fixpoint iterations then you'll get a lot of duplicated code.
