      Description

        C2 compiler is missing check for infinite loop in PhaseIdealLoop::place_near_use() and as result it crashes when trying to process it as a normal loop.

        The expected behavior of the C2 compiler is to simply bail out with "COMPILE
        SKIPPED: infinite loop (retry at different tier)". JDK8 passed the test in such way.
