>> WB_IsIntrinsicAvailable() needs additional check that the compLevel in the request is less than CompLevel_highest_tier. It actually was this way before JDK-8162881 (http://hg.openjdk.java.net/jdk9/hs-comp/hotspot/rev/a2e73f79284b), but then it was change to check only for TieredStopAtLevel. But the former is not necessarily less or equal to CompLevel_highest_tier, which in client VM leads to a failure when asking the question about higher levels.
