    Description

      The fix for JDK-8236522 contained the partial/broken fix for a missing barrier issue that was already fixed by JDK-8238780. As a result, tests are failing:

      compiler/valhalla/valuetypes/TestIntrinsics.java macosx-x64-debug Exception: java.lang.RuntimeException: Expected to get exit value of [0]

      The changes to valuetypenode.cpp/hpp should be reverted.
