redundant_guards suggests change that doesn't compile for matching on CStr

[Supreeeme]

Summary

Clippy emits a suggestion that doesn't compile when matching on a CStr.

Lint Name

redundant_guards

Reproducer

I tried this code:

fn main() {
    match c"hi" {
        x if x == c"hi" => (),
        _ => ()
    }
}

I saw this happen:

warning: redundant guard
 --> src/main.rs:3:14
  |
3 |         x if x == c"hi" => (),
  |              ^^^^^^^^^^
  |
  = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#redundant_guards
  = note: `#[warn(clippy::redundant_guards)]` on by default
help: try
  |
3 -         x if x == c"hi" => (),
3 +         c"hi" => (),
  |

Making this change does not compile:

error: cannot use unsized non-slice type `CStr` in constant patterns
 --> src/main.rs:3:9
  |
3 |         c"hi" => (),
  |         ^^^^^
