evolve: unrelated parts of splits are no longer considered content-divergent

Let's backport e68fe567a780 from core that improves content-divergence
computation. This way we can both provide a better experience to evolve
extension users on older Mercurial versions, and don't have to fix evolve tests
for hg 6.1 that we use for one of our CI jobs.

Content divergence and trying to relocate a node on top of itself (issue5958)

  $ hg init issue5958

  $ echo hi > r0
  $ hg ci -qAm 'add r0'
  $ echo hi > foo.txt
  $ hg ci -qAm 'add foo.txt'
  $ hg metaedit -r . -d '0 2'
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved

(Make changes in unrelated files so that we don't have any merge conflicts
during the rebase, but the two touched revisions aren't identical)
