Improve doc about `map_clone`

A follow up of https://github.com/rust-lang/rust-clippy/issues/6239#issuecomment-719100677.

`map_clone` works with not only `Iterator` but `Option` although not written in [doc](https://rust-lang.github.io/rust-clippy/master/#map_clone). Also, an example in the doc shows  a usage of dereferencing, but this isn't also written.

changelog: Improve doc about `map_clone`

ad4f82997a Auto merge of #6119 - rsulli55:find_is_some_on_strs, r=flip1995 
Add a case to `lint_search_is_some` to handle searching strings

Fixes: #6010

This adds a lint which recommends using `contains()` instead of `find()` followed by `is_some()` on strings as suggested in #6010.

This was added as an additional case to
5af88e3c2d/clippy_lints/src/methods/mod.rs (L3037)

I would really appreciate any comments/suggestions for my code!

27a15721c5 Rollup merge of #79016 - fanzier:underscore-expressions, r=petrochenkov 
Make `_` an expression, to discard values in destructuring assignments

This is the third and final step towards implementing destructuring assignment (RFC: rust-lang/rfcs#2909, tracking issue: #71126). This PR is the third and final part of #71156, which was split up to allow for easier review.

With this PR, an underscore `_` is parsed as an expression but is allowed *only* on the left-hand side of a destructuring assignment. There it simply discards a value, similarly to the wildcard `_` in patterns. For instance,
```rust
(a, _) = (1, 2)
```
will simply assign 1 to `a` and discard the 2. Note that for consistency,
```
_ = foo
```
is also allowed and equivalent to just `foo`.

Thanks to ````@varkor```` who helped with the implementation, particularly around pre-expansion gating.

add error_occured field to ConstQualifs,

fix #76064

I wasn't sure what `in_return_place` actually did and not sure why it returns `ConstQualifs` while it's sibling functions return `bool`. So I tried to make as minimal changes to the structure as possible. Please point out whether I have to refactor it or not.
