7046182: G1: remove unnecessary iterations over the collection set Summary: Remove two unnecessary iterations over the collection set which are supposed to prepare the RSet's of the CSet regions for parallel iterations (we'll make sure this is done incrementally). I'll piggyback on this CR the removal of the G1_REM_SET_LOGGING code. Reviewed-by: brutisso, johnc
