      Shenandoah native load barrier has code to detect if load is issued by non-Java thread, if so, it returns old oop if it is unmarked.

      This is really a hack that tries to address the issue: weak processor can trigger load barrier on GC path (JDK-8231999).

      Since, the problem was correctly fix by JDK-8232747. We should remove this hack.
