Thank you, Tobias
Changes look good.
Please, try to run at least jtreg tests with -XX:-UseLoopPredicate. There could be some code that assume that predicates exist only with UseLoopPredicate (missed LoopLimitCheck originally).

The LoopLimitCheck flag was also removed but the code in parse1.cpp and loopnode.cpp was not adapted correctly (see bug description).
