How could the tests fail because of autoformatting, you may ask?
The answer is deprecation warnings. These specify the location of the deprecated
entity, and due to autoformatting these moved around.
This turned out to be a fairly simple but easy to make bug. When we want to
figure out the value pointed-to in a multi-assignment, we look at the left hand
side to see what value from the right hand side we should assign. Unfortunately,
we accidentally attempted to look up this information in the _left hand side_ of
the assignment, resulting in no points-to information at all. The only thing
needed to fix this was to properly link up the left and right hand sides: using
the left hand side to figure out what index to look at, and then looking up the
points-to information for the corresponding place in the right hand side.
