collapsible_if lint is confused by comments and sometimes deletes them with --fix

[e00E]

Summary

fn v1(a: bool, b: bool) {
    if a {
        if b {
            todo!()
        }
    }
}

fn v2(a: bool, b: bool) {
    if a {
        // comment
        if b {
            todo!()
        }
    }
}

fn v3(a: bool, b: bool) {
    if a {
        if 
        // comment
        b {
            todo!()
        }
    }
}

fn v4(a: bool, b: bool) {
    if a {
        if b
        // comment
        {
            todo!()
        }
    }
}

v1, v3, v4 trigger the collapsible_if lint with the suggestion

if a && b {
    todo!()
}

Bug 1: It is inconsistent that v2 does not trigger the lint while v3, v4 do.
Bug 2: When automatically applying the suggestion in v3, v4 through clippy --fix the comment is removed. It is not acceptable for the suggestion to remove comments.
