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

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

Lint `manual_unwrap_or_default` for Result as well
This PR is modifying the `manual_unwrap_or_default` to be applied/linted for `Result`s as well. It is part of the fixes desired by https://github.com/rust-lang/rust-clippy/issues/12618

Fix grammer for the Safety documentation check
The original message ("unsafe function's docs miss `# Safety` section") reads quite awkwardly. I've changed it to "unsafe function's docs are missing a `# Safety` section" to have it read better.

Dedup nonminimal_bool_methods diags
Relates to #12379
Fix `nonminimal_bool` lint so that it doesn't check the same span multiple times.
`NotSimplificationVisitor` was called for each expression from `NonminimalBoolVisitor` whereas `NotSimplificationVisitor` also recursively checked all expressions.

Only run `suboptimal_flops` on inherent method calls
Fixes#12881
`suboptimal_flops` was making the wrong assumption that a `.log()` method call on a float literal must choose the inherent log method that will always have an argument present (in which case `args[0]` indexing would be fine), but that wasn't the case in the linked issue because at the point of the method call, the exact float type hadn't been inferred yet (and method selection can't select inherent methods when the exact float type has not yet been inferred, in which case it falls back to looking for trait impls and chooses the one that didn't have any parameters).
This fixes it by actually making sure it's a call to an inherent method (could also fix the linked ICE by simply using fallibly indexing via `.get()`, but this felt like it'd fix the root cause: even if there were one argument, it would still be wrong to emit a warning there because it's not the `log` method the lint was expecting). I'm not sure if we need that extra function be in `clippy_utils` but it feels like it could be useful.
changelog: Fixes an ICE in [`suboptimal_flops`]
Using Clippy as a proper noun when refering to the unique entity Clippy
I was reading some documentation (specially the book) and I notice some few usages of the word `clippy` when refering to the Project/Tool. As we already have in the majority of the documentation, in those cases, Clippy is a proper noun, and because of that should be used capitalized.
This is, for sure, not an exhaustive change: quite the opposity, it was just some cases that I could verify with not so much effort.
changelog: Docs: capitalizing the `clippy` word in some usages.
Modify str_to_string to be machine-applicable
Fixes https://github.com/rust-lang/rust-clippy/issues/12768
I'm not sure if there is any potential for edge cases with this - since it only ever acts on `&str` types I can't think of any, and especially since the methods do the same thing anyway.
changelog: allow `str_to_string` lint to be automatically applied
Disable `indexing_slicing` for custom Index impls
Fixes https://github.com/rust-lang/rust-clippy/issues/11525
Disables `indexing_slicing` for custom Index impls, specifically any implementations that also do not have a `get` method anywhere along the deref chain (so, for example, it still lints on Vec, which has its `get` method as part of the deref chain).
Thanks `@y21` for pointing me in the right direction with a couple of handy util functions for deref chain and inherent methods, saved a headache there!

fix: let non_canonical_impls skip proc marco
Fixed#12788
Although the issue only mentions `NON_CANONICAL_CLONE_IMPL`, this fix will also affect `NON_CANONICAL_PARTIAL_ORD_IMPL` because I saw
> Because of these unforeseeable or unstable behaviors, macro expansion should often not be regarded as a part of the stable API.
on Clippy Documentation and these two lints are similar, so I think it might be good, not sure if it's right or not.
