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.

Refactor MSRV aliases
changelog: Remove MSRV from `needless_question_mark` and change MSRV for `missing_const_for_fn` from 1.37.0 to 1.46.0.
First [mentioned on Zulip](https://rust-lang.zulipchat.com/#narrow/stream/257328-clippy/topic/Better.20MSRV.20testing.20idea/near/236215074).
* Moves MSRV constants into `clippy_utils::msrvs`. Now they are named to represent a stabilized feature flag or library item that is required for a lint's suggestion.
* `needless_question_mark` no longer has MSRV. Not needed since it does not suggest adding `?`.
* `missing_const_for_fn` MSRV was changed from 1.37.0 to 1.46.0. This seems to be a past mistake.
extend `single_element_loop` to match `.iter()`
This extends `single_element_loop` to also match `[..].iter()` in the loop argument. Related to #7125, but not completely fixing it due to the lint only firing if the array expression contains a local variable.

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.
Switch transmute_ptr_to_ptr to "pedantic" class.
Per discussion in https://github.com/rust-lang/rust-clippy/issues/6372, this lint has significant false positives.
changelog: transmute_ptr_to_ptr defaults to "allow".
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
