Taus Brock-Nannestad 2face94fa5 Python: Mitigate CP in nested_sequence_assign.
The problem here was that in the base case, there was no relationship between
`left_parent` and `right_parent`. These could be any two tuples or lists, even
if they were not part of an assignment statement.

To fix this, we add a bit of manual "magic", requiring that both of these
arguments must belong to the left and right-hand sides of the same assignment
statement.

(Note that this is in principle _still_ a gross overapproximation, but since
assignment statements are usually quite restricted in size, I don't expect this
to be a major problem.)
