new_ret_no_self: allow Self in inner type for impl Trait return types

Check the inner types of associated types of a trait when checking for Self in the return type of a `new` method. This means that the following will no longer warn:
```rust
trait Trait {
    type Inner;
}

struct S;

impl S {
    fn new() -> impl Trait<Inner = Option<Self>> {
        struct TraitImpl;

        impl Trait for TraitImpl {
            type Inner = Option<S>;
        }

        TraitImpl
    }
}
```
```rust
#![feature(async_await)]

struct Connection;

impl Connection {
    async fn new() -> Result<Self, ()> {
        Ok(S)
    }
}
```
closes #4359

changelog: fix `new_ret_no_self` lint for async `new` functions.

286d528a45 Auto merge of #4345 - phansch:enum_variants_fix, r=flip1995 
Don't emit enum_variant_names if remainder starts with a numeric

changelog: Fix false positive in `pub_enum_variant_names` and `enum_variant_names`

As [per the reference](https://doc.rust-lang.org/reference/identifiers.html), identifiers must start with a letter. So we don't suggest a better
variant naming in case the remainder would start with a numeric.

Fixes #739

<!--
Thank you for making Clippy better!

We're collecting our changelog from pull request descriptions.
If your PR only updates to the latest nightly, you can leave the
`changelog` entry as `none`. Otherwise, please write a short comment
explaining your change.

If your PR fixes an issue, you can add "fixes #issue_number" into this
PR description. This way the issue will be automatically closed when
your PR is merged.

If you added a new lint, here's a checklist for things that will be
checked during review or continuous integration.

- [ ] Followed [lint naming conventions][lint_naming]
- [ ] Added passing UI tests (including committed `.stderr` file)
- [ ] `cargo test` passes locally
- [ ] Executed `util/dev update_lints`
- [ ] Added lint documentation
- [ ] Run `cargo fmt`

Note that you can skip the above if you are just opening a WIP PR in
order to get feedback.
