EVALUATION

Do not remove safepoints during peeling optimization. Improve the code in IdealLoopTree::counted_loop() to eliminate all others safepoints in a loop (but not in this loop's nested loops) which have a safepoint on dominating path.

Loop peeling optimization removes needed safepoints from peeled iteration of inner loop during OSR compilation of VirtualMachineLiveLock$InterleavedTask::run() method.
