change `InlineAsmCtxt` to not talk about `FnCtxt`
wip for https://github.com/rust-lang/compiler-team/issues/529. this currently uses both the `FnCtxt` and is used by `check_mod_item_types`. This should be the only thing blocking that MCP afaict.
I am still unsure whether `rustc_hir_typeck` should depend on `rustc_hir_analysis` to use the `InlineAsmCtxt`. I think that's the best solution for now, so that's what I will go for

Point to generic or arg if it's the self type of unsatisfied projection predicate
We do this for `TraitPredicate`s in `point_at_type_arg_instead_of_call_if_possible` and `point_at_arg_instead_of_call_if_possible`, so also do it for `ProjectionPredicate`.
Improves spans for a lot of unit tests.
Simplify format_args builtin macro implementation.
Instead of a FxHashMap<Symbol, (usize, Span)> for the named arguments, this now includes the name and span in the elements of the Vec<FormatArg> directly. The FxHashMap still exists to look up the index, but no longer contains the span. Looking up the name or span of an argument is now trivial and does not need the map anymore.
Visit attributes in more places.
This adds 3 loosely related changes (I can split PRs if desired):
- Attribute checking on pattern struct fields.
- Attribute checking on struct expression fields.
- Lint level visiting on pattern struct fields, struct expression fields, and generic parameters.
There are still some lints which ignore lint levels in various positions. This is a consequence of how the lints themselves are implemented. For example, lint levels on associated consts don't work with `unused_braces`.
`Parser::parse_bottom_expr` currently constructs an empty `attrs` and
then passes it to a large number of other functions. This makes the code
harder to read than it should be, because it's not clear that many
`attrs` arguments are always empty.
This commit removes `attrs` and the passing, simplifying a lot of
functions. The commit also renames `Parser::mk_expr` (which takes an
`attrs` argument) as `mk_expr_with_attrs`, and introduces a new
`mk_expr` which creates an expression with no attributes, which is the
more common case.
fix(iter::skip): Optimize `next` and `nth` implementations of `Skip`
This avoids calling nth/next or nth/nth to first skip elements and then get the next one (unless necessary due to usize overflow).

Add tests for the drop behavior of some control flow constructs
In #100513 it was shown that the drop behaviour of let_chains is not correct currently. Since drop behaviour is something pretty subtle, this adds explicit tests for the drop behavior of `if`, `if let` and `match` to make sure that it does not regress in the future.
The `println!`s were left in to make debugging easier in case something goes wrong, but they are not required for the test.
Impl `Debug` for some structs of rustbuild
A small patch to impl `Debug` for some structs of rustbuild to make debugging easier.
(I was trying to impl `Debug` for the `Config` struct, but found to have a bit more things to do. So gave up for now.)
Fix HorizonOS regression in FileTimes
The changes in #98246 caused a regression for multiple Newlib-based systems. This is just a fix including HorizonOS to the list of targets which require a workaround.

rustdoc: Merge source code pages HTML elements together
We realized that the HTML generated for the source code pages could be improved quite a lot. This PR is a first pass toward this goal. Some explanations: it merges similar classes elements (even when there are white characters in between).
There is an exception to this: if this is an ident, I also merged it with "unclassified" elements. This part is up to debate and can be very easily removed as the check is performed in one place (in the `can_merge` function).
EDIT: The `ident` is now only kept in the code for the `span` it contains but it is not rendered into the HTML.
So now some numbers:
For these ones, on each page, I run this JS: `document.getElementsByTagName('*').length`. The goal is to count the number of DOM elements. I took some pages that seemed big, but don't hesitate to check some others.

rustc_target: Update some old naming around self contained linking
The "fallback" naming pre-dates introduction of `-Clink-self-contained`.
Noticed when reviewing https://github.com/rust-lang/rust/pull/99500.
This PR doesn't break any json target spec, but supporting per-linker-flavor startup objects needed by https://github.com/rust-lang/rust/pull/99500 will break them, so maybe next time I'll remove the compatibility names.
Add `Iterator::array_chunks` (take N+1)

I've tried to address most of the review comments on the previous attempt. The only thing I didn't address is `try_fold` implementation, I've left the "custom" one for now, not sure what exactly should it use.
