  InitializeInstanceFieldsElements ( O, constructor )
    1. Assert: Type ( O ) is Object.
    2. Assert: Assert constructor is an ECMAScript function object.
    3. If constructor.[[PrivateBrand]] is not undefined,
      a. Perform ? PrivateBrandAdd(O, constructor.[[PrivateBrand]]).
    4. Let fieldRecords be the value of constructor's [[Fields]] internal slot.
    5. For each item fieldRecord in order from fieldRecords,
      a. Perform ? DefineField(O, fieldRecord).
    6. Return.
