rebase: filter out descendants of divergence-causing commits earlier

`hg rebase` treats obsolete commits differently depending what has
happened to the commit:

 1) Obsolete commit without non-obsolete successors: Skipped, and a
 note is printed ("it has no successor").

 2) Obsolete commit with a successor in the destination (ancestor of
 it): Skipped, and a note is printed ("already in destination").

 3) Obsolete commit with a successor in the rebase set: The commit and
 its descendants are skipped, and a note is printed ("not rebasing
 <commit> and its descendants as this would cause divergence"), unless
 `allowdivergence` config set.

 4) Obsolete commit with a successor elsewhere: Error ("this rebase
 will cause divergences"), unless `allowdivergence` config set.

Before this patch, we did all those checks up front, except for (3),
which was checked later. The later check consisted of two parts: 1)
filtering out of descendants, and 2) conditionally printing message if
the `allowdivergence` config was not set. This patch makes it so we do
the filtering early.

A consequence of filtering out divergence-causing commits earlier is
that we rebase commits in slightly different order, which has some
impact on tests.
