Recent change to deleteDeadBlocksFromLoop was not enough to fix all the problems related to dead blocks after nontrivial unswitching of switches. We need to delete all the dead blocks that were created during unswitching, otherwise we will keep having problems with phi's or dead blocks. This change removes all the dead blocks that are reachable from the loop, not trying to track whether these blocks are newly created by unswitching or not. While not completely correct, we are unlikely to get loose but reachable dead blocks that do not belong to our loop nest. It does fix all the failures currently known, in particular PR38778.
