    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). iii) O is not an object,
    throw a TypeError exception
