When we replace the Phi we created with matched ones it is possible that there are two identical phi nodes in IR. And matcher is smart enough to find that new created phi matches both of them. So we try to replace our phi node with matched ones twice and what is bad we delete our phi node twice causing a crash. As soon as we found that we have two identical Phi nodes it makes sense to do a clean-up and replace one phi node by other one. The patch implements it.
