Aborting marking just before remark results in useless additional clearing of the next mark bitmap

        Description

        If before a full GC (that is already in the vm operation queue) a GC Remark happens, the VM continues to clear the next bitmap although it has already been cleared when aborting it.

        This is additional, needless work. Guard the call to _cm->clearNextBitmap() in ConcurrentMarkThread::run() with the appropriate condition.
