RFR: Add aarch64 specific lock/unlock tsan instruments

[Jie He]

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.
