[Scheduler] Adjust interface of CreateTargetMIHazardRecognizer to use ScheduleDAGMI. NFC

davemgreen · davemgreen · commit b891490ceb39 · 2020-01-15T07:21:44.000Z
All the callers of this function will be ScheduleDAGMI from the
MachineScheduler. This allows us to use the extra info available in
ScheduleDAGMI without resorting to awkward casts.
