    Assume F is a Function object. When the [[HasInstance]] method of F is called with value V and V is an object, the following steps are taken:
    i) Call the [[Get]] method of F with property name "prototype".
    ii) Let O be Result(i) and O is an object.
    iii) Let V be the value of the [[Prototype]] property of V.
    iv) If V is null, return false.
    v)  If O and V refer to the same object or if they refer to objects joined to each other (13.1.2), return true.
    vi) Go to step iii)
