Specializes calls to most Python classes. Specifically, any class that

inherits from ``object``, or another Python class, and does not override

``__new__``.
|
|

|

The specialized instruction does the following:
|
|
||||||
|
|
||||||
1. Creates the object (by calling ``object.__new__``)
|
|
||||||
2. Pushes a shim frame to the frame stack (to cleanup after ``__init__``)
|

3. Pushes the frame for ``__init__`` to the frame stack

Speeds up the instantiation of most Python classes.
