Incorrect unreachable statement warning

[ndmitchell]

Describe the Bug

def foo(x):
    for _ in x:
        return 1
    else:
        return 2 # ERROR sandbox.py:5:9-17: This `return` statement is unreachable

print(foo([]))

Python: 3.12

The second return is marked unreachable. The example shows it being reached.

Note that the related:

def foo(x):
    for _ in x:
        return 1
    else:
        return 2
    print(1)

This doesn't warn that print is unreachable, but it is.
