Sounds good! But I think it's unrelated to this PR itself and can be done in another PR. |

…=JohnTitor Integrate binary search codes of binary_search_by and partition_point For now partition_point has own binary search code piece. It is because binary_search_by had called the comparer more times and the author (=me) wanted to avoid it. However, now binary_search_by uses the comparer minimum times. (rust-lang#74024) So it's time to integrate them. The appearance of the codes are a bit different but both use completely same logic.

…ochenkov Prefer `partition_point` to look up assoc items Since we now have `partition_point` (instead of `equal_range`), I think it's worth trying to use it instead of manually finding it. `partition_point` uses `binary_search_by` internally (rust-lang#85406) and its performance has been improved (rust-lang#74024), so I guess this will make a performance difference.
