----------------
I'd like to see the logic moved into PostRAScheduler::runOnMachineFunction (so that every target does not have to explicitly check the scheduler model) along with the call to this enablePostRAScheduler function and the corresponding command-line-argument check. The interface may not really be setup correctly for this currently, but we can change it.
