Attribute assignments that come before the definition of __setattr__ don't call it #1239
Description
class C:
def __init__(self) -> None:
self.x = 0
def __setattr__(self, name: str, value: object) -> None:
print("setattr", name)
super().__setattr__(name, value)
def after(self) -> None:
self.x = 1
c = C()
c.after()Interpreted, this prints setattr x twice. Compiled with current master, it prints it once: the assignment in __init__ writes the attribute directly, without calling __setattr__. If __setattr__ is moved above __init__, it's called both times.
