Empty implementation of SchedulingPriorityQueue::dump

Hi All,

While reading SchedulePostRATDList::ListScheduleTopDown() [1], I find SchedulingPriorityQueue::dump has an empty implementation. Therefore, the following debug dump basically outputs nothing.

DEBUG(dbgs() << “\n*** Examining Available\n”; AvailableQueue.dump(this));

Not sure why we want this. Is it intended?

​I am playing around Hexagon test case, and I find it still
run PostRAscheudlerList under O2, unless I add -misched-postra option.
