Subject: (S) RFR: 8150506: Remove unused locks

I stumbled across the fact that the following locks are no longer being used in the VM:

Runtime:
  - Interrupt_lock
  - ProfileVM_lock
  - ObjAllocPost_lock

Serviceability:
  -JvmtiPendingEvent_lock

GC:
- CMark_lock
- CMRegionStack_lock

so unless there are objections I will remove them. A reviewer from each area would be appreciated.

Thanks,
David
