Improve map_entry lint
Fix false positives where the map is used before inserting into the map.
Fix false positives where two insertions happen.
Suggest using `if let Entry::Vacant(e) = _.entry(_)` when `or_insert` might be a semantic change

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?

Fixes #5835

19740d9334 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.

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.

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?

cde58f7174 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.
