`W0631:undefined-loop-variable` false positive when for loop has function call that returns `NoReturn`

[DetachHead]

Bug description

from typing import NoReturn


def fail() -> NoReturn:
    ...

def foo(l):
    while True:
        for i in l:
            break
        else:
            continue
            # or break
            # or fail()
        print(i)

this is the same issue as #5971, though it seems to have only been fixed for return statements but not break, continue statements or function calls that return NoReturn or Never

I'd be in favor of adding break and continue to the list of nodes checked in the PR for #6480.

Would you be interested to prepare a PR?

[DetachHead]

@jacobtylerwalls i've opened #7318, however i would like to also try to fix the NoReturn example but i'm not sure how

[DanielNoord]

@DetachHead Do you want to work on the NoReturn example? I can guide you through it if you want.

If you get the FunctionDef node of fail by inferring the call to it you can use the type_comment_returns attribute to get the return type annotation. With an inference on that annotation + a check for .qualname() == "typing.NoReturn I think we should be able to add this case as well.

@DanielNoord i gave it a go but i can't figure out how to get the FunctionDef from the function call. #7419
