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 FP in `single_component_path_imports` lint
Fix FP in `single_component_path_imports` lint when the import is reused with `self`, like in `use self::module`.

Fix false-positive `debug_assert` in `panic`
This fixes a false-positive in `clippy::panic` when `debug_assert` is used with a message.
Fixes https://github.com/rust-lang/rust-clippy/issues/7062.

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?

Use `register_renamed` instead of `register_removed` for uplifted lints
This still applies the lint, and also adds a structured suggestion to
rename it.

Invalid null usage v2
This is continuation of #6192 after inactivity.
I plan to move paths into the compiler as diagnostic items after this is merged.

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.
