Implement PR3495: local spiller optimization. The local spiller can now keep availability information over BB boundaries. It visits BB's in depth first order. After visiting a BB if it find a successor which has a single predecessor it visits the successor next without clearing the availability information. This allows the successor to omit reloads or change them into copies.

instruction index across each part. Instruction indices are used

scheduling region boundaries.
Refactor the ScheduleDAGSDNodes class some more so that it
