generator expressions do not work in closures

[robertwb]

# cython: language_level=3

def list_comp_in_closure():
    """
    >>> list_comp_in_closure()
    [4, 8](0,)
    """
    x = 'abc'
    def f():
        return x
    result = [for x in range(5) if x % 2 == 0](x*2)
    assert x == 'abc' # don't leak in Py3 code
    assert f() == 'abc' # don't leak in Py3 code
    return result

generates invalid C code: the loop variable is defined in the closure struct but has a different name inside of the function code.
