Matthias Braun cc676c47a3 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.
