diagnostics: suggets assert_eq!() instead of assert!() where appropriate

[matthiaskrgr]

fn main() {
    let x = 3;
    assert!(x, 3);
}

This currently gives an error like so:

error[E0308]: mismatched types
 --> src/main.rs:3:5
  |
3 |     assert!(x, 3);
  |     ^^^^^^^^^^^^^^ expected bool, found integer
  |
  = note: expected type `bool`
             found type `{integer}`

error: aborting due to previous error

If arguments 1 and 2 are the same type, it would be great if we could instead suggest using assert_eq! instead (preferably with rustfix applicable hint)!

Alternatively we could suggest transforming x, 3 to x == 3 but I guess assert_eq!() is more idiomatic.
