GCNDownwardRPTracker RPTracker.reset() skips debug instructions for NextMI so RPTracker.getNext() will give the beginning of a sched region if it is a debug value. In this case we will never set the live-ins for that block.

Add check to see if getNext also equals the MI after skipping debug instructions.
