instanceof: return false instead of throwing

[ChangeLog][Important Behavior Changes] Using instanceof to check
whether an instance has the type of QObject or one of its derived
classes used to raise a TypeError, if the instance was not derived from
QObject. Now, it instead returns false, which is more in line with the
ECMAScript semantic.
