Extract and reuse logic controlling behaviour of overflow checking assertions instead of duplicating it three times.

…it-to-assoc-ty

Very minor thing that I happened to notice in passing, but it's both shorter and means it gets `mul nuw`, so why not.

Fixes rust-lang#85410

This makes it easier to profile.

- Skip files in `skip` wherever possible to avoid reading their contents - Don't look for `tidy-alphabetic-start` in tests. It's never currently used and slows the check down a lot. - Add new `filter_not_rust` helper function

Previously, it would walk each directory twice: once in the main `Walk` iterator, and once to count the number of entries in the directory. Now it only walks each directory once.

This has a significant speedup for me locally, from about 1.3 seconds to .9 seconds.

Error code E0794 for late-bound lifetime parameter error. This PR addresses [rust-lang#80618](rust-lang#80618).

Speed up tidy quite a lot I highly recommend reviewing this commit-by-commit. Based on rust-lang#106440 for convenience. ## Timings These were collected by running `x test tidy -v` to copy paste the command, then using [`samply record`](https://github.com/mstange/samply). before (8 threads) ![image](https://user-images.githubusercontent.com/23638587/222965319-352ad2c8-367c-4d74-960a-e4bb161a6aff.png) after (8 threads) ![image](https://user-images.githubusercontent.com/23638587/222965323-fa846f4e-727a-4bf8-8e3b-1b7b40505cc3.png) before (64 threads) ![image](https://user-images.githubusercontent.com/23638587/222965302-dc88020c-19e9-49d9-a87d-cad054d717f3.png) after (64 threads) ![image](https://user-images.githubusercontent.com/23638587/222965335-e73d7622-59de-41d2-9cc4-1bd67042a349.png) The last commit makes tidy use more threads, so comparing "before (8 threads)" to "after (64 threads)" is IMO the most realistic comparison. Locally, that brings the time for me to run tidy down from 4 to .9 seconds, i.e. the majority of the time for `x test tidy` is now spend running `fmt --check`. r? `@the8472`
