Add test for a list comprehension that is nested in the left-hand part 

of another list comp.  This caused crashes reported as SF bugs 409230
and 407800.

Note that the new tests are in a function so that the name lookup code
isn't affected by how many *other* list comprehensions are in the same
scope.
