Stefan Pintilie f220e7cb76 [PowerPC] Replace the Post RA List Scheduler with the Machine Scheduler
We want to run the Machine Scheduler instead of the List Scheduler after RA.
  Checked with a performance run on a Power 9 machine with SPEC 2006 and while
  some benchmarks improved and others degraded the geomean was slightly improved
  with the Machine Scheduler.
