5e8c0c5ae0 Auto merge of #5441 - rabisg0:fix/clone-on-copy, r=phansch 
Check for clone-on-copy in argument positions

Earlier if arguments to method calls matched the above pattern they were
not reported. This patch ensures such arguments are checked as well.

Fixes #5436

changelog: apply clone_on_copy lint to func args as well

Check fn header along with decl when suggesting to implement trait

When checking for functions that are potential candidates for trait
implementations check the function header to make sure modifiers like
asyncness, constness and safety match before triggering the lint.

Rollup merge of #5420 - dtolnay:newret, r=flip1995 
Downgrade new_ret_no_self to pedantic

As motivated by #5418. This is the second most widely suppressed Clippy style lint, and [this grep.app search](https://grep.app/search?q=%5C%5Ballow%5C%28.%2Aclippy%3A%3Anew_ret_no_self%5Cb&regexp=true&case=true&filter[lang][0]=Rust) shows a large number of diverse reasonable signatures for a `new` method.

Rollup merge of #5415 - nickrtorres:master, r=flip1995 
Add new lint for `Result<T, E>.map_or(None, Some(T))`

Fixes #5414

PR Checklist
---
- [x] Followed lint naming conventions (the name is a bit awkward, but it seems to conform)
- [x] Added passing UI tests (including committed .stderr file)
- [x] cargo test passes locally
- [x] Executed cargo dev update_lints
- [x] Added lint documentation
- [x] Run cargo dev fmt

`Result<T, E>` has an [`ok()`](https://doc.rust-lang.org/std/result/enum.Result.html#method.ok) method that adapts a `Result<T,E>` into an `Option<T>`.
It's possible to get around this adapter by writing `Result<T,E>.map_or(None, Some)`.

This lint is implemented as a new variant of the existing [`option_map_none` lint](https://github.com/rust-lang/rust-clippy/pull/2128)

Rollup merge of #5412 - dtolnay:tostring, r=flip1995 
Downgrade inefficient_to_string to pedantic

From the [documentation](https://rust-lang.github.io/rust-clippy/master/index.html#inefficient_to_string):

> ```diff
> - ["foo", "bar"].iter().map(|s| s.to_string());
>
> + ["foo", "bar"].iter().map(|&s| s.to_string());
> ```

I feel like saving 10 nanoseconds from the formatting machinery isn't worth asking the programmer to insert extra `&` / `*` noise in the *vast* majority of cases. This is a pedantic lint.

Fix syntax highlighting of code fence 
The documentation for RESULT_EXPECT_USED includes this code:

    let res: Result<usize, ()> = Ok(1);
    res?;
    # Ok::<(), ()>(())

Because the code fence didn't start with `rust`, the code wasn't highlighted and the line starting with `#` was displayed on the website. This is now fixed.
