Peel blocks and statements utils
changelog: none
* Rename `remove_blocks` to `peel_blocks`
* Add `peel_blocks_and_stmts`
* Various refactors to use the above utils
* The utils also now check `block.rules`
Parenthesize blocks in `needless_bool` suggestion
Because the `if .. {}` statement already puts the condition in expression scope, contained blocks would be parsed as complete
statements, so any `&` binary expression whose left operand ended in a block would lead to a non-compiling suggestion.
We identify such expressions and add parentheses. Note that we don't make a difference between normal and unsafe blocks because the parsing problems are the same for both.
This fixes#8052.

Fix some false negatives for [`single_char_pattern`]
*Please write a short comment explaining your change (or "none" for internal only changes)*
changelog: Fix some false negatives for [`single_char_pattern`]
I noticed that clippy wasn't complaining about my usage of `split_once("x")` in a personal project so I updated the list of functions.
I had to update the test case for an unrelated issue because replace is now included in the list of functions to be linted.

The documentation also states that the author/assignee will be pinged. However, this doesn't seem to be the case, it at least hasn't done so for me and in this [PR](https://github.com/rust-lang/rust/pull/90642#issuecomment-962465404)

Consider NonNull as a pointer type
PR 1/2 for issue #8045. Add `NonNull` as a pointer class to suppress false positives like `UnsafeCell<NonNull<()>>`. However, this change is not sufficient to handle the cases shared in gtk-rs and Rug in the issue.

Escape backslash in single_char_pattern.rs
Escape backslash in single_char_pattern.
Previously, the proposed clippy fix for a single backslash in raw strings ```r"\"``` or ```r#"\"#``` was also only an unescaped, *single* ```'\'```:
```shell
warning: single-character string constant used as pattern
2 | let s = r#"abc\xyz/"#.find(r"\");
| ^^^^ help: try using a `char` instead: `'\'`
|
= note: `#[warn(clippy::single_char_pattern)]` on by default
```
This PR corrects this to a properly escaped *double* backslash ```'\\'```.
I haven't come up with any other problematic cases, a single quote was already handled.
Closes: #8060
changelog: Escape backslash in ``[`single_char_pattern`]``
Fix `any()` not taking reference in `search_is_some` lint
`find` gives reference to the item, but `any` does not, so suggestion is broken in some specific cases.
Fixes: #7392
changelog: [`search_is_some`] Fix suggestion for `any()` not taking item by reference
Cleanup: Eliminate ConstnessAnd
This is almost a behaviour-free change and purely a refactoring. "almost" because we appear to be using the wrong ParamEnv somewhere already, and this is now exposed by failing a test using the unstable `~const` feature.
We most definitely need to review all `without_const` and at some point should probably get rid of many of them by using `TraitPredicate` instead of `TraitRef`.
This is a continuation of https://github.com/rust-lang/rust/pull/90274.
