MachineScheduler: Remember top/bottom choice in bidirectional scheduling
Remember the last choice for the top/bottom scheduling boundary in
bidirectional scheduling mode. The top choice should not change if we
schedule at the bottom and vice versa.
This allows us to improve compiletime: We only recalculate the best pick
for one border and re-use the cached top-pick from the other border.
