5a21a8c4dd 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.
