single_match suggestion causes deny-by-default eq-op warning

[matthiaskrgr]

Description

slightly amused:

#[derive(Eq, PartialEq)]
pub struct Data([u8; 4]);

const DATA: Data = Data([1, 2, 3, 4]);

fn main() {
    match DATA {
        DATA => (),
        _ => (),
    }
}

=>

7  | /     match DATA {
8  | |         DATA => (),
9  | |         _ => (),
10 | |     }
   | |_____^ help: try: `if DATA == DATA { () }`

the suggested code however:

error: equal expressions as operands to `==`
 --> a.rs:7:8
  |
7 |     if DATA == DATA { () }
  |        ^^^^^^^^^^^^
  |
