So, some context for this, well, more a story. I'm not used to scripting, I've never really scripted anything, even if it's a valuable skill. I just never really needed it. Now, `@flip1995` correctly suggested using a script for this in `rust-clippy#7813`...
And I decided to write a script using nushell because why not? This was a mistake... I spend way more time on this than I would like to admit. It has definitely been more than 4 hours. It shouldn't take that long, but me being new to scripting and nushell just wasn't a good mixture... Anyway, here is the script that creates another script which adds the versions. Fun...
Just execute this on the `gh-pages` branch and the resulting `replacer.sh` in `clippy_lints` and it should all work.
```nu
mv v0.0.212 rust-1.00.0;
mv beta rust-1.57.0;
mv master rust-1.58.0;
let paths = (open ./rust-1.58.0/lints.json | select id id_span | flatten | select id path);
let versions = (
ls | where name =~ "rust-" | select name | format {name}/lints.json |
each { open $it | select id | insert version $it | str substring "5,11" version} |
group-by id | rotate counter-clockwise id version |
update version {get version | first 1} | flatten | select id version);
$paths | each { |row|
let version = ($versions | where id == ($row.id) | format {version})
let idu = ($row.id | str upcase)
$"sed -i '0,/($idu),/{s/pub ($idu),/#[clippy::version = "($version)"]\n pub ($idu),/}' ($row.path)"
} | str collect ";" | str find-replace --all '1.00.0' 'pre 1.29.0' | save "replacer.sh";
```
And this still has some problems, but at this point I just want to be done -.-
`match_overlapping_arm` refactoring
The main purpose of this pull request is to remove the unneeded and scary `unimplented!()` in the `match_arm_overlapping` code.
The rest is gratuitous refactoring.

Fix `explicit_counter_loop` suggestion for non-usize types
changelog: Add a new suggestion for non-usize types in [`explicit_counter_loop`]
closes: #7920
Fix suggestion for deref expressions in redundant_pattern_matching

closes: #7921
Only the end bounds of ranges can actually be included or excluded. This
commit changes the SpannedRange type to reflect that. Update `Kind::value`
to and `Kind::cmp` for this change. `Kind::cmp` gets flipped to check value
first and then the bound details and is much shorter.
This unbounded case never actually happens because `all_ranges(..)` uses
the scrutinee type bounds for open ranges. Switch to our own `Bound`
enum so that we don't have this case.
Introduce `expr_visitor` and `expr_visitor_no_bodies`
changelog: none
A couple utils that satisfy a *lot* of visitor use cases. Factoring in every possible usage would be really big so I just focused on cleaning clippy_utils.
Replace `in_macro` usage with `from_expansion`
changelog: none
Generally replace `in_macro(span)` with `span.from_expansion()`. If we're just trying to avoid expanded code, this seems more appropriate because any kind of expanded code is prone to false positives. One place I did not touch is `macro_use.rs`. I think this lint could use a rewrite so I moved `in_macro` there, the only place it is still used.
Move non_ascii_literal to restriction
It feels like the more apt category, since cases where you'd want it enabled would be pretty specific
changelog: Move [`non_ascii_literal`] to `restriction`
Prevent clippy::needless_lifetimes false positive in async function definition
Scan `OpaqueDef` bounds for lifetimes as well. Those `OpaqueDef` instances are generated while desugaring an `async` function definition.
This fixes#7893

Fix manual_assert and match_wild_err_arm for `#![no_std]` and Rust 2021
Rust 2015 `std::panic!` has a wrapping block while `core::panic!` and Rust 2021 `std::panic!` does not. See rust-lang/rust#88919 for details.
Note that the test won't pass until clippy changes in rust-lang/rust#88860 is synced.

Unseparated literal suffix
Closes#7658
Since `literal_suffix` style is opinionated, we should disable by default and only enforce if it's stated as so.
changelog: [`unseparated_literal_suffix`] is renamed to `literal_suffix`, adds a new configuration `literal-suffix-style` to enforce a certain style writing literal_suffix. Possible values for `literal-suffix-style`: `"separated"`, `"unseparated"`
avoid linting `possible_truncation` on bit-reducing operations

*Please write a short comment explaining your change (or "none" for internal only changes)*
changelog: avoid linting `possible_truncation` on bit-reducing operations
`unseparated_literal_suffix`
This commit adds a configuration `literal-suffix-style` to enforce a
specific style for unseparated_literal_suffix. The configuration accepts
two values:
- "separated"
enforce all literals to be written separately (e.g. `123_i32`)
- "unseparated"
enforce all literals to be written as unseparated (e.g. `123i32`)
Not specifying a value means that there is no preference on style and
any style should not be warned.
Disable "if_not_else" lints from firing on else-ifs
Fixes#7892
1. Convert `['if_not_else']` to `LateLintPass` and use `clippy_utils::is_else_clause` for checking.
2. Update tests.
changelog: [`if_not_else`] now ignores else if statements.
1. Convert IfNotElse to LateLintPass and use clippy_utils::is_else_clause for checking.
2. Handle the case where the span comes from desugaring.
3. Update tests.
