    Step 4 of defineProperty calls the [[DefineOwnProperty]] internal method
    of O passing 'true' for the Throw flag. In this case, step 3 of
    [[DefineOwnProperty]] requires that it throw a TypeError exception when
    current is undefined and extensible is false. The value of desc does not
    matter.
