`bool_to_int_with_if` bad fix suggestion for `if let`

[alexheretic]

Summary

When auto-fixing a particular bool_to_int_with_if the code fix does not compile. The current suggestion does not seem to work with if let.

Reproducer

I tried this code:

enum Kind {
    A,
    #[allow(dead_code)]
    B,
}

fn main() {
    let kind = Kind::A;
    let kind_num = if let Kind::A = kind { 1u8 } else { 0 };
    eprintln!("{kind_num}");
}

This produces the following bad suggestion.

let kind_num = u8::from(let Kind::A = kind);
