Jonas Paulsson e451eeff5c [PostRA scheduling] Allow a target to do scheduling when it wants post RA. ...

SystemZ needs to do its scheduling after branch relaxation, which can
only happen after block placement, and therefore the standard
PostRAScheduler point in the pass sequence is too early.

TargetMachine::targetSchedulesPostRAScheduling() is a new method that
signals on returning true that target will insert the final scheduling
pass on its own.
