Auto merge of #7075 - xFrednet:7054-fp-branches-sharing-code, r=camsteffen,flip1995
Fixing FPs for the `branches_sharing_code` lint
Fixes #7053
Fixes #7054
And an additional CSS adjustment to support dark mode for every inline code. It currently only works in paragraphs, which was an oversight on my part :sweat_smile:. [Current Example](https://rust-lang.github.io/rust-clippy/master/index.html#blacklisted_name)
This also includes ~50 lines of doc comments and is therefor not as big as the changes would indicate. :penguin:

changelog: none
All of these bugs were introduced in this dev version and are therefor not worth a change log entry.

Auto merge of #6568 - Jarcho:redundant_pattern_matching, r=flip1995
Fix: redundant_pattern_matching drop order
Fixes #5746
A note about the change in drop order is added when the scrutinee (or any temporary in the expression) isn't known to be safe to drop in any order (i.e. doesn't implement the `Drop` trait, or contain such a type). There is a whitelist for some `std` types, but it's incomplete. Currently just `Vec<_>`, `Box<_>`, `Rc<_>` and `Arc<_>`, but only if the contained type is also safe to drop in any order.
Another lint for when the drop order changes could be added as allowed by default, but the drop order requirement is pretty subtle in this case. I think the note added to the lint should be enough to make someone think before applying the change.
changelog: Added a note to `redundant_pattern_matching` when the change in drop order might matter
Still need to handle the value returned by `insert` correctly.
changelog: Improve `map_entry` suggestion. Will now suggest `or_insert`, `insert_with` or `match _.entry(_)` as appopriate.
changelog: Fix `map_entry` false positives where the entry api can't be used. e.g. when the map is used for multiple things.
Auto merge of #7085 - Jarcho:manual_map_autoderef, r=giraffate
Don't allow adjustments for `manual_map`
fixes: #7077
The other option here would be to add the return type to the closure. It would be fine for simple types, but longer types can be rather unwieldy. Could also implement the adjustment manually.
changelog: Don't lint `manual_map` when type adjustments are added. e.g. autoderef

Auto merge of #7049 - Jarcho:remove_match_path, r=camsteffen
Remove `match_path` and `match_qpath`
The only remaining usage is the `author` lint, so the functions are left in for now. The test result for `repl_uninit` changed, the lint was broken before.
The `collapsible_span_lint_calls` and `match_type_on_diag_item` tests have been changed. Both lints were broken when utils was extracted into it's own crate. `match_type_on_diag_item` isn't quite fixed, but it's at least less broken.

Remove all usages of `match_path`, `match_qpath` and `match_path_ast` except the `author` lint.

Auto merge of #7039 - phansch:melt-ice, r=flip1995
tabs_in_doc_comments: Fix ICE due to char indexing
This is a quick-fix for an ICE in `tabs_in_doc_comments`. The problem
was that we we're indexing into possibly multi-byte characters, such as '位'.
More specifically `get_chunks_of_tabs` was returning indices into
multi-byte characters. Those were passed on to a `Span` creation that
then caused the ICE.
This fix makes sure that we don't return indices that point inside a
multi-byte character. *However*, we are still iterating over unicode
codepoints, not grapheme clusters. So a seemingly single character like y̆ ,
which actually consists of two codepoints, will probably still cause
incorrect spans in the output. But I don't think we handle those cases
anywhere in Clippy currently?
Auto merge of #7076 - rail-rain:missing_const_for_fn, r=phansch
Fix a FP in `missing_const_for_fn`
where a function that calls a standard library function whose constness
is unstable is considered as being able to be a const function. Fixes #5995.
The core change is the move from `rustc_mir::const_eval::is_min_const_fn` to `rustc_mir::const_eval::is_const_fn`. I'm not clear about the difference in their purpose between them so I'm not sure if it's acceptable to call `qualify_min_const_fn::is_min_const_fn` this way now.

Auto merge of #7074 - camsteffen:diag-methods, r=llogiq
Split `is_diagnostic_assoc_item`
changelog: none
* Split `is_diagnostic_assoc_item` into `is_diag_item_method` and `is_diag_trait_item`
* `is_diag_item_method` is a bit more nuanced with the `tcx.type_of(impl_id).ty_adt_def()` step, so it seems better to keep that separate.
* No need to generalize over traits and Adt's since we know which one we want at compile time
* "item" vs. "method" because a trait may have associated items.
* Replaces the usage of the `sym::slice` diagnostic item with the `slice_alloc` lang item. The diagnostic item should be removed from rustc because it is on the `slice_alloc` impl, not slice itself (and it's not needed).

Fix FP in `wrong_self_convention` lint
Previously, this lint didn't check into impl block when it was implementing a trait.
Recent improvements (#6924) have moved this check and some impl blocks are now checked but they shouldn't, such as in #7032.

Add a note on the issue #5953
Hello,
I thought it would be better to have a note and warning about this issue considering it introduced an UB in the past even with the "Search on Github" feature.

Auto merge of #7060 - daxpedda:debug-assert-panic-in-result-fn, r=flip1995
Remove `debug_assert` from `panic_in_result_fn`
I couldn't find any documentation on `debug_assert` that should be remove.
In my humble opinion, I would also like to argue that `todo` and `unreachable` shouldn't trigger this lint?
Rollup merge of #83916 - Amanieu:asm_anonconst, r=petrochenkov
Use AnonConst for asm! constants
This replaces the old system which used explicit promotion. See #83169 for more background.
The syntax for `const` operands is still the same as before: `const <expr>`.
Fixes #83169
Because the implementation is heavily based on inline consts, we suffer from the same issues:
- We lose the ability to use expressions derived from generics. See the deleted tests in `src/test/ui/asm/const.rs`.
- We are hitting the same ICEs as inline consts, for example #78174. It is unlikely that we will be able to stabilize this before inline consts are stabilized.
Auto merge of #6931 - Jarcho:needless_borrow, r=phansch,flip1995
Fix all occurences `needless_borrow` internally
The bug that got 'needless_borrow' moved into the nursery was fixed two years ago in d4370f8b.
This did trigger over a thousand times internally, so that's all the other changes. I vetted most of them, but there's a lot The only interesting change is to the lint list. `declare_tool_lint` already makes a reference, so there's no need to take a reference to the lints.
