Fix stack overflow issue in `redundant_pattern_matching`
Fixes#7169
~~cc `@Jarcho` Since tomorrow is release day and we need to get this also fixed in beta, I'll just revert the PR instead of looking into the root issue. Your changes are good, so if you have an idea what could cause this stack overflow and know how to fix it, please open a PR that reverts this revert with a fix.~~
r? `@llogiq`
changelog: none (fixes stack overflow, but this was introduced in this release cycle)

[single_char_pattern] add strip_prefix and strip_suffix
Title says it all. Adjusted ui tests.
I added the second commit in case you don't like that I moved that table into `single_char_pattern.rs` directly. I don't see any reason why it shouldn't be in that file. It isn't used anywhere else.
*Please write a short comment explaining your change (or "none" for internal only changes)*

while_immutable_cond: check condition for mutation
This fixes#6689 by also checking the bindings mutated in the condition, whereas it was previously only checked in the loop body.

Fix FN in `iter_cloned_collect` with a large array
fixes#6808
changelog: Fix FN in `iter_cloned_collect` with a large array
I spotted that [is_iterable_array](a362a4d1d0/clippy_lints/src/loops/explicit_iter_loop.rs (L67-L75)) function that `explicit_iter_loop` lint is using only works for array sizes <= 32.
There is this comment:
> IntoIterator is currently only implemented for array sizes <= 32 in rustc
I'm a bit confused, because I read that [IntoIterator for arrays](https://doc.rust-lang.org/src/core/array/mod.rs.html#194-201) with const generic `N` is stable since = "1.0.0". Although Const Generics MVP were stabilized in Rust 1.51.
Should I set MSRV for the current change? I will try to test with older compilers soon.

Unused io amount detects `.read().ok()?`

changelog: unused_io_amount now detect expertion like `.read().ok()?`, `.read().or_else(|err| ...)?` and similar expressions.
Better suggestions when returning macro calls.
Suggest changeing all the break expressions in a loop, not just the final statement.
Don't lint divergent functions.
Don't suggest returning the result of any divergent fuction.
Add lint to check for boolean comparison in assert macro calls
This PR adds a lint to check if an assert macro is using a boolean as "comparison value". For example:
```rust
assert_eq!("a".is_empty(), false);
```
Could be rewritten as:
```rust
assert!(!"a".is_empty());
```
PS: The dev guidelines are amazing. Thanks a lot for writing them!
changelog: Add `bool_assert_comparison` lint
useless use of format! should return function directly
fixes#7066
