RFR: 8337318: Deoptimization::relock_objects fails assert(monitor->owner() == Thread::current()) failed: must be [v2]

[Coleen Phillimore]

> The assert is wrong.  During deoptimization, the locking_thread is not the current thread, and that's the thread we should assert is the owner.
> Reproduced in tier8 with com/sun/jdi/EATests.java, with LockStack CAPACITY=1 and not reproduced with the fix.
