Match expressions panic during SSA flattening if they're on a runtime value with > 2 branches

[jfecher]

Aim

fn main(x: Field) {
    match x {
        1 => println(1),
        2 => println(1),
        3 => println(3),
        x => println(x),
    }
}

Expected Behavior

The value of x to be printed

Bug

The application panicked (crashed).
Message:  internal error: entered unreachable code: return encountered before a join point was found. This can only happen if early-return was added to the language without implementing it by jmping to a join block first
