Don't lint indexing_slicing lints on proc macros
This pr fixes https://github.com/rust-lang/rust-clippy/issues/12824
Even though the issue mentions the indexing case only, it was easy to apply the fix to the slicing case as well.
changelog: [`out_of_bounds_indexing`, `indexing_slicing`]: Don't lint on procedural macros.
Handle single chars with `to_string()` for `single_char_add_str`
Add support for single chars / literals with `to_string()` call for `push_str()` and `insert_str()`.
changelog: [`single_char_add_str`]: handle single chars with `to_string()` call
Closes#12775
Normalize type aliases when checking significant drops.
fixes#10750
No test as I'm not sure exactly how the type alias caused a stack overflow here. Also removes an unnecessary `HashSet`.

- remove now dead code in ASSERTIONS_ON_CONSTANTS
cc #11966
- Partially revert "ignore `assertions-on-constants` in const contexts"
This reverts commit c7074de420a2192fb40d3f2194a20dd0d1b65cc6.
Don't lint blocks in closures for blocks_in_conditions
Seemed like an outlier for the lint which generally caught only the syntactically confusing cases, it lints blocks in closures but excludes closures passed to iterator methods, this changes it to ignore closures in general
changelog: none
Remove `lazy_static` mention
I planned to replace any mention with `LazyLock` but I think `thread_local` is more appropriate here - `const`s that aren't `Sync` wouldn't be able to go in a `lazy_static`/`static LazyLock` either
Also removed a test file that was mostly commented out so wasn't testing anything

Make `for_each_expr` visit closures by default, rename the old version `for_each_expr_without_closures`
A lot of the time `for_each_expr` is picked when closures should be visited so I think it makes sense for this to be the default with the alternative available for when you don't need to visit them.
The first commit renames `for_each_expr` to `for_each_expr_without_closures` and `for_each_expr_with_closures` to `for_each_expr`
The second commit switches a few uses that I caught over to include closures to fix a few bugs

Handle const effects inherited from parent correctly in `type_certainty`
This fixes a (debug) ICE in `type_certainty` that happened in the [k256 crate]. (I'm sure you can also specifically construct an edge test case that will run into type_certainty false positives visible outside of debug builds from this bug)
<details>
<summary>Minimal ICE repro</summary>
```rs
use std::ops::Add;
Add::add(1_i32, 1).add(i32::MIN);
```
</details>
The subtraction here overflowed:
436675b477/clippy_utils/src/ty/type_certainty/mod.rs (L209)
... when we have something like `Add::add` where `add` fn has 0 generic params but the `host_effect_index` is `Some(2)` (inherited from the parent generics, the const trait `Add`), and we end up executing `0 - 1`.
(Even if the own generics weren't empty and we didn't overflow, this would still be wrong because it would assume that a trait method with 1 generic parameter didn't have any generics).
So, *only* exclude the "host" generic parameter if it's actually bound by the own generics

Revert: create const block bodies in typeck via query feeding
as per the discussion in https://github.com/rust-lang/rust/pull/125806#discussion_r1622563948
It was a mistake to try to shoehorn const blocks and some specific anon consts into the same box and feed them during typeck. It turned out not simplifying anything (my hope was that we could feed `type_of` to start avoiding the huge HIR matcher, but that didn't work out), but instead making a few things more fragile.

Revert "Disallow ambiguous attributes on expressions" on nightly
As discussed in [today's t-compiler meeting](https://rust-lang.zulipchat.com/#narrow/stream/238009-t-compiler.2Fmeetings/topic/.5Bweekly.5D.202024-06-06/near/443079505), this reverts PR #124099 to fix P-critical beta regressions #125199.
r? ``@wesleywiser``
Opening as draft so that ``@wesleywiser`` and ``@apiraino,`` you can tell me whether you wanted:
1. a `beta-accepted` revert of #124099 on nightly (this PR)? That will need to be backported to beta (even though #126093 may be the last of those)
2. a revert of #124099 on beta?
3. all of the above?
I also opened #126102, another draft PR to revert #124099 on beta, should you choose options 2 or 3.
