Currently G1 may repeatedly clears claim marks during full gc.
This is unnecessary if different claim marks for different phases (mark phase, adjust phase) different to the claim value used for concurrent marking are used.
This removes the need to clear claim marks twice during full gc.
(The clearing at the end is necessary to prepare for concurrent mark)
