ScheduleDAGInstrs doesn't behave differently before or after register
allocation. So there should be no need for the IsPostRA flag; It was only
used in a method of MachineSchedulerBase which behaved differently in
MachineScheduler/PostMachineScheduler. Change this to let
MachineScheduler/PostMachineScheduler just pass in a
parameter to that function.
