Fedor Sergeev 7b49aa03af [SimpleLoopUnswitch] After unswitch delete dead blocks in parent loops
Summary:
Assert from PR38737 happens on the dead block inside the parent loop
after unswitching nontrivial switch in the inner loop.

deleteDeadBlocksFromLoop now takes extra care to detect/remove dead
blocks in all the parent loops in addition to the blocks from original
loop being unswitched.
