8230706: Waiting on completion of strong nmethod processing causes long pause times with G1
...
Instead of globally waiting for completion of strong nmethod processing during evacuation, synchronize the nmethods processing on a per-nmethod basis so that only one thread processes one nmethod at once using a state. This state indicates what work (strong/weak processing) needs to be done and what has already been done.
