Denying `non_canonical_clone_impl` and `implicit_return` is incompatible

[ElementW]

Summary

Implicit returns are evil in my book and the non_canonical_*_impl are good to have, but this is a repeat of #12683 because #12702 only fixed the ordering half of those, not the clone half.

Lint Name

non_canonical_clone_impl

Reproducer

I tried this code:

#![deny(clippy::non_canonical_clone_impl)]
#![deny(clippy::implicit_return)]
#![allow(clippy::needless_return)]

pub struct Container<T: Copy> {
    pub value: T,
}

impl<T: Copy> Copy for Container<T> {}

impl<T: Copy> Clone for Container<T> {
    fn clone(&self) -> Self {
        return *self;
    }
}

I saw this happen:

error: non-canonical implementation of `clone` on a `Copy` type
  --> src/main.rs:12:29
   |
12 |       fn clone(&self) -> Self {
   |  _____________________________^
13 | |         return *self;
14 | |     }
   | |_____^ help: change this to: `{ *self }`

  --> src/main.rs:1:9
   |
 1 | #![deny(clippy::non_canonical_clone_impl)]
   |         ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

If Clippy's suggestion is applied, the following happens instead:

error: missing `return` statement
  --> src/main.rs:13:9
   |
13 |         *self
   |         ^^^^^
   |
   = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#implicit_return
note: the lint level is defined here
  --> src/main.rs:2:9
   |
 2 | #![deny(clippy::implicit_return)]
   |         ^^^^^^^^^^^^^^^^^^^^^^^
help: add `return` as shown
   |
13 |         return *self
   |         ++++++

The suggestion there just sends you back to square one.

I expected to see this happen:

Lint passes, and non_canonical_clone_impl

	implicit_return allowed	implicit_return denied
needless_return allowed	allows both	requires return *self;
needless_return denied	requires *self	implodes?
