revsfromrange: reuse information from the stablesort
We collaborate with the stablesort to store the order that led to a merge. That
way, when we needs to retrieve revision from that merge we can reuse that order.
We might need to filter to only retains ancestors of the merge we care about but
skipping the stablesort safe a large amount of time.
