Seems unrelated to my PR, can reproduce locally both on PR branch and on main |

Yes, that's a flaky test. I closed and reopened the PR to rerun CI. |

constify DoubleEndedIterator The only functions that can't be constified are `advance_back_by` (requires const range or const-hack), `nth_back` (requires `advance_back_by`), and `rfind` (requires const closures). I've put it under `const_iter`, but I can open a separate tracking issue, though I think tracking all `Iterator` traits separately would be quite annoying, and we probably would prefer to constify them together anyway.
