Auto merge of #37378 - petrochenkov:nopat, r=eddyb
Prohibit patterns in trait methods without bodies
They are not properly type checked
```rust
trait Tr {
fn f(&a: u8); // <- This compiles
}
```
, mostly rejected by the parser already and generally don't make much sense.
This PR is kind of a missing part of https://github.com/rust-lang/rust/pull/35015.
Given the [statistics from crater](https://github.com/rust-lang/rust/pull/37378#issuecomment-256154994), the effect of this PR is mostly equivalent to improving `unused_mut` lint.
