  Add aarch64 specific lock/unlock instruments into interpreter and
  runtime.
  
  Update an assertion in aarch64 due to different memory layout.
  
  With tsan enabled, too small java stack often causes SOE, especially
  thread "process reaper". Therefore, for running jtreg test in aarch64,
  we have to set jdk.lang.processReaperUseDefaultStackSize as true.
