The expansion of `asm!()` and `line!()` is not marked as from an expansion, in which case `SourceMap::stmt_span` returns the input span unchanged. So instead of using `stmt_span`, use `mac_call_stmt_semi_span` directly
Allow to go through clippy lints page without javascript
Fixes#13536.
This is the follow-up of https://github.com/rust-lang/rust-clippy/pull/13269.
This PR makes it possible to expand/collapse lints (individually) without JS. To achieve this result, there are two ways:
1. Use `details` and `summary` tags. Problem with this approach is that the web browser search may open the `details` tags automatically if content matching it is inside. From a previous discussion with `@Alexendoo,` it seems to not be a desired behaviour.
2. Use a little trick where you use a `label` and a checkbox where the checkbox is in fact hidden. Then it's just a matter of CSS.

Remove `GenKillAnalysis`
There are two kinds of dataflow analysis in the compiler: `Analysis`, which is the basic kind, and `GenKillAnalysis`, which is a more specialized kind for gen/kill analyses that is intended as an optimization. However, it turns out that `GenKillAnalysis` is actually a pessimization! It's faster (and much simpler) to do all the gen/kill analyses via `Analysis`. This lets us remove `GenKillAnalysis`, and `GenKillSet`, and a few other things, and also merge `AnalysisDomain` into `Analysis`. The PR removes 500 lines of code and improves performance.
r? `@tmiasko`
The URLs contained an extra `clippy_lints`, which resulted in
broken links. Links are generated using each lint's `id_location`,
which already contains the full path inside the repository.
Change the category of `manual_is_power_of_two` to `pedantic`
Fixes#13547.
The value being checked might be a bit flag, suggesting `is_power_of_two` for it would make the code unreadable.

Add lint for unnecessary lifetime bounded &str return
Closes#305.
Currently implemented with a pretty strong limitation that it can only see the most basic implicit return, but this should be fixable by something with more time and brain energy than me. Cavets from #13388 apply, as I have not had a review on my clippy lints yet so am pretty new to this.

Add `&pin (mut|const) T` type position sugar
This adds parser support for `&pin mut T` and `&pin const T` references. These are desugared to `Pin<&mut T>` and `Pin<&T>` in the AST lowering phases.
This PR currently includes #130526 since that one is in the commit queue. Only the most recent commits (bd450027eb4a94b814a7dd9c0fa29102e6361149 and following) are new.

Use correct std/core prefix in lint output
changelog: none
I was waiting for #13452 to be merged before sending this one. `std` is used instead of `core` when appropriate in messages.
Move `clippy::module_name_repetitions` to `restriction` (from `pedantic`)
Rational:
- Too pedantic IMO, I use `#[warn(pedantic)]` in my personal projects, but then always allow this lint. The fact that we had a few `#[expect(clippy::module_name_repetitions)]` also underlines this point IMO
- STD doesn't do this either. Examples:
- std::vec::Vec
- std::collections::vec_deque::VecDequeue
- #7666 commonly ignored

[#13541](https://github.com/rust-lang/rust-clippy/pull/13541)
Fix lint `manual_slice_size_calculation` when a slice is ref more than once
When a slice is ref more than once, current suggestion given by `manual_slice_size_calculation` is wrong. For example:
```rs
let s: &[i32] = &[1, 2][..];
let ss: &&[i32] = &s; // <-----
let _ = size_of::<i32>() * ss.len();
```
clippy now suggests:
```patch
- let _ = size_of::<i32>() * ss.len();
+ let _ = size_of_val(ss);
```
However, this can result in calculating the size of `&[i32]`, instead of `[i32]` (this wrong suggestion also leads to `size_of_ref` warning: https://rust-lang.github.io/rust-clippy/master/index.html#/size_of_ref )
Now I am sending this PR to fix this bug, so that clippy will suggest (some deref added):
```patch
- let _ = size_of::<i32>() * ss.len();
+ let _ = size_of_val(*ss);
```
As I am not familiar with current clippy code-base, please correct me if I am not doing well or I can do it better :)

[`implicit_saturating_sub`] Fix suggestion with a less volatile approach
Related to #13533, such and obvious mistake got pass my watch, quite embarassing :/
Revert #13533 and implement a more robust solution.

Check MethodCall/Call arg count earlier or at all
This gets rid of a bunch of possible panic spots, as well as bailing out earlier for optimisation reasons.
I started doing this because I saw that a significant amount of time was being spent in the `create_dir` restriction lint when running clippy with `perf`, but this also helps with robustness.
