…=jieyouxu rustc_borrowck: Don't suggest changing closure param type not under user control This changes output of a handful of tests more than the one added in the first commit, but as far as I can tell, all removed suggestions were invalid. Closes rust-lang#128381 which is **D-invalid-suggestion** with two 👍-votes.

…r=Urgau Run `eval_config_entry` on all branches so we always emit lints Fixes rust-lang#149090 Ideally I'd have liked to fix this issue using rust-lang#149215, and this is still the long term plan, but this is slightly more annoying to implement than I'd have liked to, and this is also a nice and easy solution to the problem. r? `@tgross35`

How to interpret the job duration changes?

Job durations can vary a lot, based on the actual runner instance
that executed the job, system noise, invalidated caches, etc. The table above is provided
mostly for t-infra members, for simpler debugging of potential CI slow-downs.
