rustdoc: remove unused CSS `#implementations-list > h3 > span.in-band`
This was added in 51f26acaea 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 34bd2b845b to have `<code class='in-band'>`, making this CSS unused.
Then it was turned into a `<div>` in 9077d540da without issue.
Finally, the header itself acquired the `in-band` class in 76a3b609d0.
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 96d4137dee, 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 😅
Fixes#9431.
The current `range_plus_one` and `range_minus_one` suggestions
are completely incorrect when macros are involved.
This commit resolves this by disabling the lints for any range
expression that is expanded from a macro. The reasons for this
are that it is very difficult to create a correct suggestion in
this case and that false negatives are less important for
pedantic lints.
This CSS was added in 5e01ba36c9, 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.

This was added in 9077d540da to override the
style on `<div>` tags that were acting as headers. These `<div>` tags were
replaced with `<section>` tags in 32f62607c3,
but this CSS was probably already redundant even then (the headers had
already been replaced with real `<h3>` and `<h4>` tags in
76a3b609d0).
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.
Use HashStable_Generic in rustc_type_ir
A lot of the types in this crate implemented HashStable directly to avoid circular dependencies. One way around that is to use HashStable_Generic. We adopt that here to avoid a lot of boilerplate.
This doesn't update all the types, because some would require `I: Interner + HashStable`.
r? `@cjgillot`
rustc: Parameterize `ty::Visibility` over used ID
It allows using `LocalDefId` instead of `DefId` when possible, and also encode cheaper `Visibility<DefIndex>` into metadata.
Avoid UB in the Windows filesystem code in... bootstrap?
This basically a subset of the changes from https://github.com/rust-lang/rust/pull/101171. I didn't think to look in src/bootstrap for more windows filesystem API usage, which was apparently a mistake on my part. It's kinda goofy that stuff like this is in here, but what are you gonna do, computers are awful.
I also added `winbase` to the `winapi` dep -- I tested this in a tmp crate but needed to add this to your Cargo.toml -- you `use winapi::stuff::winbase` in this function, but are relying on something else turning on that feature.
