FN implicit if_same_then_else

fn main() {
	println!("{:?}", func(4));
}

fn func(n: i32) -> bool {
	if n < 2 {
		return true;
	} else if  n > 2 {
		return false;
	}
	return false; // return outside of conditions
}

this code is basically identical to

fn main() {
	println!("{:?}", func(4));
}

fn func(n: i32) -> bool {
	if n < 2 {
		return true;
	} else if  n > 2 {
		return false;
	} else { // return moved into else {}
		return false;
	}
}

but only the latter triggers the if_same_then_else warning.
Should the first example trigger a warning as well?

Start by locating the if_same_then_else lint and its existing tests, then compare how the two Rust examples are analyzed. Add a regression case for the first example if it should produce the same warning, and run the lint's tests to verify the result.
