This removes the ICE codepaths for `f16` and `f128` in Clippy.
`rustc_apfloat` is used as a dependency for the parsing of these types,
since their `FromStr` implementation will not be available in the
standard library for a while.
Add more types to `is_from_proc_macro`
I've been running through going through all the lint implementations to clean them up. I'll be separating out the changes into small PRs to make reviewing easier.

Add myself back to reviewer rotation
Hey 👋
Even though I might have less time than usual, $DAY_JOB soon and working on Cosmographic Software for fun, I think I want to get back in the swing of things here

Lint `manual_unwrap_or` for it let cases
This PR modifies `manual_unwrap_or` to lint for `if let` cases as well. This effort is part of the fixes desired by https://github.com/rust-lang/rust-clippy/issues/12618
changelog:[`manual_unwrap_or`]: Lint for `if let` cases.
Rework `octal_escapes`
Main changes are not doing UTF-8 decoding, noting each occurrence as an individual lint emission, and narrowing the span to point to the escape itself.

Fix ICE in `upper_case_acronyms`
fixes#12284
The logic has been rewritten to avoid allocations. The old version allocated multiple vecs and strings for each identifier. The new logic allocates a single string only when the lint triggers.
This also no longer lints on strings which don't start with an uppercase letter (e.g. `something_FOO`).

Pause assignments to @xFrednet for summer break 🏖️
I'm only removing myself from the assignment roulette as I want to allow `r? xFrednet` for `gh-pages` and other updates. So feel free to still `r?` me.

Add lint `manual_inspect`
fixes#12250
A great example of a lint that sounds super simple, but has a pile of edge cases.

changelog: Add lint `manual_inspect`
* Delay the parsing of the use node
* Mark when the `SyntaxContext` changes rather than return `None`
* Return a default value if the HIR tree is broken rather than `None`
Add field_scoped_visibility_modifiers lint

Also rewrites it to use `ureq` to drop some heavy dependencies as `crates_io_api` brings in `reqwest`

Avoid emitting `assigning_clones` when cloned data borrows from the place to clone into
Fixes#12444Fixes#12460Fixes#12749Fixes#12757Fixes#12929
I think the documentation for the function should describe what- and how this is fixing the issues well.
It avoids emitting a warning when the data being cloned borrows from the place to clone into, which is information that we can get from `PossibleBorrowerMap`. Unfortunately, it is a tiny bit tedious to match on the MIR like that and I'm not sure if this is possibly relying a bit too much on the exact MIR lowering for assignments.
Things left to do:
- [x] Handle place projections (or verify that they work as expected)
- [x] Handle non-`Drop` types

Fix doc nits
Clippy is wonderful, and reading its lints is a great way to learn about Rust. While doing this, I noticed a few little copyedits, such as adding trailing periods to sentences, or tweaking wording very slightly to improve its readability. I hope you will accept these suggestions as an act of love for the project, with my thanks for all the maintainers' hard work.

When both `std::` and `core::` items are available, only suggest the
`std::` ones. We ensure that in `no_std` crates we suggest `core::`
items.
Ensure that the list of items suggested to be imported are always in the
order of local crate items, `std`/`core` items and finally foreign crate
items.
Tweak wording of import suggestion: if there are multiple items but they
are all of the same kind, we use the kind name and not the generic "items".
Fix#83564.
Let `qualify_min_const_fn` deal with drop terminators
Fixes#12677
The `method_accepts_droppable` check that was there seemed overly conservative.
> Returns true if any of the method parameters is a type that implements `Drop`.
> The method can't be made const then, because `drop` can't be const-evaluated.
Accepting parameters that implement `Drop` should still be fine as long as the parameter isn't actually dropped, as is the case in the linked issue where the droppable is moved into the return place. This more accurate analysis ("is there a `drop` terminator") is already done by `qualify_min_const_fn` [here](f5e250180c/clippy_utils/src/qualify_min_const_fn.rs (L298)), so I don't think this additional check is really necessary?
Fixing the other, second case in the linked issue was only slightly more involved, since `Vec::new()` is a function call that has the ability to panic, so there must be a `drop()` terminator for cleanup, however we should be able to freely ignore that. [Const checking ignores cleanup blocks](https://github.com/rust-lang/rust/blob/master/compiler/rustc_const_eval/src/transform/check_consts/check.rs#L382-L388), so we should, too?

Add lint to check manual pattern char comparison
This PR adds a new lint asked in https://github.com/rust-lang/rust-clippy/issues/12490
This lint catches manual char comparison in pattern of string functions and propose to use `char` or array of `char` instead.
As it's my first contribution i'm not feeling very safe about not matching too much or missing some cases.
Thanks in advance for taking time to review and propose feedback !
changelog: new lint [`manual_pattern_char_comparison`]
