chore: add simple comment for `get_enclosing_block`
I was reading the code of `clippy_utils/src/lib.rs` and thought that adding comment on `get_closing_block` would be helpful to first time visitor.

don't lint field_reassign when field in closure
fixes#10136
This change makes the ContainsName struct visit all interior expressions, which means that ContainsName will return true even if `name` is used in a closure within `expr`.

chore: fix identation of `if_chain` in `filter_map`
This is a really small fix.
If someone could take a look at it, I would appreciate it🙏

Move `mutex_atomic` to `restriction`
By #4295, the general consensus seems to be that `mutex_atomic` is not a useful lint in most cases. If anything, it could be useful as a restriction on code that for whatever reason can't use atomics. Keeping it in `clippy::nursery` is harmful to people attempting to use clippy for soundness.

fix incorrect suggestion in `suboptimal_flops`
fixes#10003
There was an error when trying to negate an expression like `x - 1.0`. We used to format it as `-x - 1.0` whereas a proper negation would be `-(x - 1.0)`.
Therefore, we add parentheses around the expression when it is `ExprKind::Binary`.
We also add parentheses around multiply and divide expressions, even though this is not strictly necessary.

This patch not only improves visibility, but also fixes a potential bug.
When a lint description ends with code block, the string will have three
backquotes at the end.
Since the current implementation prints the default value immediately
after that, the markdown renderer is unable to properly close the code
block.
Add size_of_ref lint
This addresses #9995, which is likely raising a valid point about `std::mem::size_of_val()`: It's [very easy to use double-references as the argument](https://github.com/apache/arrow-datafusion/pull/4371#discussion_r1032385224), which the function will happily accept and give back the size of _the reference_, not the size of the value _behind_ the reference. In the worst case, if the value matches the programmer's expectation, this seems to work, while in fact, everything will go horribly wrong e.g. on a different platform.
The size of a `&T` is independent of what `T` is, and people might want to use `std::mem::size_of_val()` to actually get the size of _any_ reference (e.g. via `&&()`). I would rather suggest that this is always bad behavior, though ([instead](https://doc.rust-lang.org/reference/type-layout.html#pointers-and-references-layout), [and](https://doc.rust-lang.org/stable/std/primitive.usize.html#associatedconstant.BITS)). I, therefore, put this lint into `correctness`.
Since the problem is usually easily fixed by removing extra `&`, I went light on suggesting code.
