[PATCH] D19350: MachineScheduler: Remember top/bottom choice in bidirectional scheduling

atrick added a comment.

Are you handling the case when the previous Top pick is scheduled at the bottom and vice-versa? I'm afraid the Candidate is keeping a pointer to a potentially already scheduled instruction.
