      Description

        Several customers have complained about clean up task takes longer time than they should be. The current source print the break down time when TraceSafepoint is on. But TraceSafepoint is a develop flag and also will enable printing a lot of information regarding safepoint. So this CR needs to address the exposure of these times and also make sure as less overheads as possible.

        The solution is to have a new flag "-XX:+TraceCleanupTimeInSafepoint" and print out the time spent in each clean up tasks when that is on. The time stamp will also be printed out when PrintGCTimeStamp is on.
