Fix indentation of website code snippets
Fixes#13568
Follow up to #13359, I didn't catch that it swapped the `strip_prefix` out for a `trim` but they aren't interchangeable here
changelog: none
docs: Fix too_long_first_doc_paragraph: line -> paragraph
The documentation for too_long_first_doc_paragraph incorrectly says "line" where it should say "paragraph".
Fix a minor typo: doscstring -> docstring.
Also do a few tiny edits to attempt to make the wording slightly shorter and clearer.
changelog: [`too_long_first_doc_paragraph`]: Edit documentation
Add units/unit prefixes of frequency to doc-valid-idents
These units/unit prefixes often come up in the embedded world.
Should this PR also modify the `test_units` test? It seems only concerned with data units currently; should it also test frequency units?
changelog: [`doc_markdown`]: Add MHz, GHz, and THz to `doc-valid-idents`.
Fix not working lint anchor (generation and filtering)
As spotted by `@flip1995,` the anchor button is currently not working. Problem was the JS that was preventing the web browser from adding the hash at the end of the URL.
For the second bug fixed, the JS was stripping two characters instead of just stripping the `#` at the beginning.

Add debug assertions for empty replacements and overlapping spans
rustc has debug assertions [^1] [^2] that check that a substitution doesn't have an empty suggestion string and an empty span at the same time, as well as that spans in multipart suggestions don't overlap.
However, since we link to the rustc-dev distributed compiler, these debug assertions are always disabled and so we never actually run them.
This leads to the problem that the debug ICE is not necessarily caught in the PR and only triggered in the rust repo sync, and in one of the last syncs this was a blocker and delayed the sync by several weeks because the fix was not obvious.
So this PR essentially copies the checks over and runs them in clippy debug builds as well, so that we can catch these errors in PRs directly.
-----
As for the second commit, this also *did* cause an ICE in a sync before and was fixed in the sync PR (see https://github.com/rust-lang/rust/pull/120345#issuecomment-1911005554), but it seems like that commit didn't make it back into the clippy repo (cc `@flip1995),` so the fixed code is in the rust repo but not in the clippy repo.

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.
changelog: [`manual_is_power_of_two`]: Change the category to `pedantic`
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.
