Shortcut BTreeBuilder.iter_entries when there are no backing indices.
It turns out that the keys.difference_update was taking a significant amount of time.
When branching bzr.dev from a stacked into a standalone, 84/180 seconds was spent
just in that difference_update.
My guess is that difference_update always scales with the number of entries in the
target set, even when the source set is small.
