cbdf17c884 Auto merge of #8707 - OneSignal:await-invalid-types, r=llogiq 
Add `await_holding_invalid_type` lint

changelog: [`await_holding_invalid_type`]

This lint allows users to create a denylist of types which are not allowed to be
held across await points. This is essentially a re-implementation of the
language-level [`must_not_suspend`
lint](https://github.com/rust-lang/rust/issues/83310). That lint has a lot of
work still to be done before it will reach Rust stable, and in the meantime
there are a lot of types which can trip up developers if they are used
improperly.

I originally implemented this specifically for `tracing::span::Entered`, until I discovered #8434 and read the commentary on that PR. Given this implementation is fully user configurable, doesn't tie clippy to any one particular crate, and introduces no additional dependencies, it seems more appropriate.

Rework `#[clippy::dump]` attribute for debugging

Hey `@rust-lang/clippy,` this adds a new `#[clippy::print_hir]` attribute that prints the node to the console using `{:#?}`. Personally, I use print debugging quite a lot while working on Clippy, and this is a simple shortcut that also works in the playground (Once this has been synced). The question is now, if we want to have this attribute. Are there any concerns? I think it's similar to our `#[clippy::author]` attribute.

I haven't added a test, as the `.stdout` file would require updates with every HIR change inside rustc. Here are some examples, for the current implementation

3d43826e32 Auto merge of #8305 - camsteffen:util-cleanup, r=flip1995 
Factor out several utils, add `path_def_id`

changelog: none

This is generally an effort to reduce the total number of utils. `path_def_id` is added which I believe is more "cross-cutting" and also complements `path_to_local`. Best reviewed one commit at a time.

Added:
* `path_def_id`
* `path_res`

Removed:
 * `is_qpath_def_path`
 * `match_any_diagnostic_items`
 * `expr_path_res`
 * `single_segment_path`
 * `differing_macro_contexts`
 * `is_ty_param_lang_item`
 * `is_ty_param_diagnostic_item`
 * `get_qpath_generics`

Renamed:
* `path_to_res` to `def_path_res`
* `get_qpath_generic_tys` to `qpath_generic_tys`

CC `@Jarcho` since this relates to some of your work and you may have input.

8f481167da Auto merge of #90986 - camsteffen:nested-filter, r=cjgillot 
Replace `NestedVisitorMap` with generic `NestedFilter`

This is an attempt to make the `intravisit::Visitor` API simpler and "more const" with regard to nested visiting.

With this change, `intravisit::Visitor` does not visit nested things by default, unless you specify `type NestedFilter = nested_filter::OnlyBodies` (or `All`). `nested_visit_map` returns `Self::Map` instead of `NestedVisitorMap<Self::Map>`. It panics by default (unreachable if `type NestedFilter` is omitted).

One somewhat trixty thing here is that `nested_filter::{OnlyBodies, All}` live in `rustc_middle` so that they may have `type Map = map::Map` and so that `impl Visitor`s never need to specify `type Map` - it has a default of `Self::NestedFilter::Map`.

55fa2ea00c Auto merge of #92816 - tmiasko:rm-llvm-asm, r=Amanieu 
Remove deprecated LLVM-style inline assembly

The `llvm_asm!` was deprecated back in #87590 1.56.0, with intention to remove
it once `asm!` was stabilized, which already happened in #91728 1.59.0. Now it
is time to remove `llvm_asm!` to avoid continued maintenance cost.

Closes #70173.
Closes #92794.
Closes #87612.
Closes #82065.
