Hi @xbolva00!

Could you please take a look on slightly updated changes? The previous version didn't preserve LoopInfo in case of new loops are created during a peeling, that causes a fail on EXPENSIVE_CHECKS builds. It's fixed now by recursively creating corresponding Loop objects by cloneLoop() utility function (moved from LoopUnswitch.cpp to LoopUtils.cpp to reuse).
