Fix single_match lint being emitted when it should not (#13765)
We realized when running `clippy --fix` on rustdoc (PR comment
[here](https://github.com/rust-lang/rust/pull/133537/files#r1861377721))
that some comments were removed, which is problematic. This PR checks
that comments outside of `match` arms are taken into account before
emitting the lint.

fix version attribute for arbitrary_source_item_ordering lint (#13819)
fix #13818

The `arbitrary_source_item_ordering` lint does not exist in v1.82.0, so
I think it needs to be fixed.

Fix: fixed multipart_suggestion in index_refutable_slice uitest (#13727)
This should address #13099 for the derivable_impls test. As this
combines everything into a single multipart_suggestion, the feedback
message is a little less "targeted" than it was before, but now it
provides a complete`--fix`able suggestion - e.g.:

```
error: this binding can be a slice pattern to avoid indexing
  --> tests/ui-toml/max_suggested_slice_pattern_length/index_refutable_slice.rs:5:17
   |
LL |     if let Some(slice) = slice {

   |
note: the lint level is defined here
  --> tests/ui-toml/max_suggested_slice_pattern_length/index_refutable_slice.rs:1:9
   |
LL | #![deny(clippy::index_refutable_slice)]
   |         ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
help: replace the binding and indexed access with a slice pattern
   |
LL ~     if let Some([_, _, _, _, _, _, _, slice_7, ..]) = slice {
LL |
LL |         // This would usually not be linted but is included now due to the
LL |         // index limit in the config file
LL ~         println!("{}", slice_7);

Move top-level files to mod.rs when applicable (#13732)
There are two modules in `clippy_utils` that are currently in the form
of:

```
src/
  | ast_utils/
  | ty/
  |
  | ast_utils.rs
  | ty.rs
```

This PR moves the top-level modules to become `mod.rs`, within their
respective folders.

```
src/
  | ast_utils/
  |   | mod.rs
  |
  | ty/
  |   | mod.rs
```

This reduces clutter in the `src` folder, and makes it easier to find
related files in certain editors.[^0] This also appears to be the
standard used in other crates in this repository, though I looked very
briefly.

I do realize that this is a style / opinionated change, so I'll close it
if it receives much push-back. :)

[^0]: I use VSCode, which groups all folders together and all files
separately. This means that `ty.rs` is quite "far" away from the `ty/`
folder, which makes it move difficult to navigate between the two.

update borrow_as_ptr to suggest &raw syntax (#13689)
This PR updates the `borrow_as_ptr` lint to no longer suggest `addr_of!`
and `addr_of_mut!` and instead use the preferred `&raw const` and `&raw
mut` syntax.

Not sure about two things:
1. Do I need to set or update a MSRV for the lint anywhere?
2. There is a `borrow_as_ptr_no_std` test as well as a `borrow_as_ptr`
test. They used to be more relevant as the lint needed to select `std`
or `core`, but that is gone now, so maybe the `borrow_as_ptr_no_std`
should be deleted?

doc_nested_refdefs: new lint for suspicious list syntax (#13707)
https://github.com/rust-lang/rust/issues/133150

This is more likely to be intended as an intra-doc link than it is to be
intended as a refdef. If a refdef is intended, it does not need to be
nested within a list item.

```markdown
- [`LONG_INTRA_DOC_LINK`]: this
  looks like an intra-doc link,
  but is actually a refdef.
  The first line will seem to
  disappear when rendered as HTML.

Fix shadow_unrelated's behaviour with closures (#13677)
Fixes https://github.com/rust-lang/rust-clippy/issues/10780

We correctly no longer give a warning when a closure is passed to a
method, where one of the arguments to that method uses the variable
which would be shadowed by an argument to that closure.
Uses is defined loosely as any expression used in the calling expression
mentions the shadowee binding (except for the closure itself):

```rust
#![deny(clippy::shadow_unrelated)]
let x = Some(1);
let y = x.map(|x| x + 1);
```
will now succeed.

See https://github.com/linebender/xilem/pull/745 - without this change,
all of the `expect(shadow_unrelated)` in the repository are met; with
it, none of them are.
