Throws a RangeError when custom calendar method returns inconsistent result

8. Repeat 3 times:
...
g. If _sign_ = 0, or _timeSign_ = 0, or _sign_ = _timeSign_, then
...
viii. Return ? CreateNormalizedDurationRecord(_dateDifference_.[[Years]],
_dateDifference_.[[Months]], _dateDifference_.[[Weeks]],
_dateDifference_.[[Days]], _norm_).
h. Set _dayCorrection_ to _dayCorrection_ + 1.
9. NOTE: This step is only reached when custom calendar or time zone methods
return inconsistent values.
10. Throw a *RangeError* exception.
