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
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.

Add a note for pre-expansion passes

Just had to turn away a PR for using pre-expansion. I don't think that was the first time. So hopefully this will inform people sooner.

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?

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.

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.
Fixes#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.

Deprecate `filter_map`
Since #6591, `filter_map` does not even lint `filter().map()`. The cases that are still linted make no sense IMO. So this just removes/deprecates it.

Fix false-positive `debug_assert` in `panic`
This fixes a false-positive in `clippy::panic` when `debug_assert` is used with a message.

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?

rename it.

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.
