JVMState should not be shared between SafePointNodes

    Description

      The following assert fails when added to SafePointNode::Ideal because SafePointNodes are often cloned without cloning the linked JVMState:
      assert(_jvms == NULL || ((uintptr_t)_jvms->map() & 1) || _jvms->map() == this, "inconsistent JVMState");

      This leads to problems like JDK-8261037.
