decimal_literal_representation suggestion drops type suffixes

The suggestion below doesn't include the usize suffix.

```
#[warn(clippy::decimal_literal_representation)]

fn main() {
    let _ = 32_773usize;
}
```
```
warning: integer literal has a better hexadecimal representation
 --> src/main.rs:4:13
  |
4 |     let _ = 32_773usize;
  |             ^^^^^^^^^^^ help: consider: `0x8005`
  |
```
I'm busy with the fix for this.
