Make `Debug` impl for `Term` useful
because `Term { ptr: 78942378998734298342, maker: PhantomData, }` does not excel at communicating the necessary information
rustdoc: remove unused CSS `div.impl-items > div`
This was added in 9077d540da944c41678a7129e04e7fc5d7e38582 to override the style on `<div>` tags that were acting as headers. These `<div>` tags were replaced with `<section>` tags in 32f62607c3142dfc9eb56a0bd72dee298ca43358, but this CSS was probably already redundant even then (the headers had already been replaced with real `<h3>` and `<h4>` tags in 76a3b609d0b93c5d8da5e4e3db37bd03e5cb1c30).
rustdoc: remove unused CSS `#implementations-list > h3 > span.in-band`
This was added in 51f26acaea46afd630fbab4ca441748802d20670 to help with the display of an `<h3>` tag that has a `<span class='in-band'>` inside.
The way implementation lists were rendered was changed in 34bd2b845b3acd84c5a9bddae3ff8081c19ec5e9 to have `<code class='in-band'>`, making this CSS unused.
Then it was turned into a `<div>` in 9077d540da944c41678a7129e04e7fc5d7e38582 without issue.
Finally, the header itself acquired the `in-band` class in 76a3b609d0b93c5d8da5e4e3db37bd03e5cb1c30.
Normalize before erasing late-bound regions in `equal_up_to_regions`
Normalize erasing regions **first**, before passing the type through a `BottomUpFolder` which erases late-bound regions too.
The root cause of this issue is due to 96d4137deed6c52c6db2dd19568c37d1c160f1e7, which removes a `normalize_erasing_regions` that happens before this call to `equal_up_to_regions`. While reverting that commit might be a fix, I think it was suspicious to be erasing late-bound regions first _then_ normalizing types in the first place in `equal_up_to_regions`.

I am tempted to ask the reviewer to review and `r+` this without a UI test, since the existing issues that I think this fixes are all incredibly difficult to minimize (anything hyper/warp related, given the nature of those libraries 😓) or impossible to reproduce locally (the miri test), namely:
* This recently reported issue with tokio + warp: #101430
* This issue from `@RalfJung` about Miri being broken: #101344
* This additional issue reported in a comment by `@tmandry` (issue with fuchsia + hyper): https://github.com/rust-lang/rust/issues/101344#issuecomment-1235974564
I have locally verified that the repro in #101430 is fixed with this PR, but after a couple of hours of attempting to minimize this error and either failing to actually repro the ICE, or being overwhelmed with the number of traits and functions I need to inline into a UI test, I have basically given up. Thoughts are appreciated on how best to handle this.
r? `@oli-obk` who is at the intersection of MIR and types-related stuff who may be able to give advice 😅
This CSS was added in 5e01ba36c9f1037c4cf3e7421413fc6c41f85d05, and served to
override CSS right above it that set a 5px padding for several kinds of
buttons in the same toolbar.
The CSS that it overrode is still there, but now it only applies to
`#settings-menu > a`, so there's nothing to override.

Allow lint passes to be bound by `TyCtxt`
This will allow storing things like `Ty<'tcx>` inside late lint passes. It's already possible to store various id types so they're already implicitly bound to a specific `TyCtxt`.
r? rust-lang/compiler
Adjust and slightly generalize operator error suggestion
(in no particular order)
* Stop passing around a whole extra `ProjectionPredicate`
* Add spaces around `=` in `Trait<..., Output = Ty>` suggestion
* Some code clean-ups, including
* add `lang_item_for_op` to turn a `Op` into a `DefId`
* avoid `SourceMap` because we don't really need to render an expr
* Remove `TypeParamVisitor` in favor of just checking `ty.has_param_types_or_consts` -- this acts a bit differently, but shouldn't cause erroneous suggestions (actually might generalize them a bit)
* We now suggest `Output = Ty` in the `where` clause suggestion when we fail to add `Struct<T>` and `T`.
I can split this out into more PRs if needed, but they're all just miscellaneous generalizations, changes, and nitpicks I saw when messing with this operator code.
translations(rustc_session): migrates rustc_session to use SessionDiagnostic - Pt. 2
# Description
This is the second part of the `rustc_session` [migration](https://github.com/rust-lang/rust/issues/100717#issuecomment-1220279883).
**Please only review this [commit](5018581957) that belongs to the part 2. The other ones are from the PR [#100753](https://github.com/rust-lang/rust/pull/100753) that is not yet merged.**
In this PR, we migrate the files `session.rs` and `config.rs`.
Please not that we have to `allow` the lints rules in some functions from `session.rs` because they are (at least I believe) part of the diagnostic machinery.
const_generics: correctly deal with bound variables
removes the hack in `resolve` which was needed because we evaluated constants without caring about their bound variables.
Each commit should be fairly self-contained, even if they build on each other

This commit removes the allows rules for the SessionDiagnostic lint
that were being used in the session.rs file.
Thanks to the PR #101230 we do not need to annotate the methods with
the allow rule as they are part of the diagnostic machinery.
