Before this patch, if a user defined the __new__() function for a class then two instances of that class would be created: once before __new__ is called and once during the __new__ call (assuming the user creates some instance, eg using super().__new__, which is most of the time). The first one was then discarded. This refactor makes it so that a new instance is only created if the user __new__ function doesn't exist.
