Please review this small change to add a hook in the G1 evacuation path.
This allows extension code to register regions which are otherwise
interesting to the GC and get notifications when pointers into such
regions are encountered.
Testing: JPRT, gc test suite
This additional branch in G1ParScanClosure introduces a slight
regression of about 1-2% in GC pause times. I have some performance
fixes to make up for that regression in the pipe.
