  Recommit "[ConstraintElim] Treat ConstantPointerNull as constant offset 0."

This reverts commit 58286f9c665ad4aa748779d559f2f296de704094.

Now with the test correctly updated.

Original message:
    Treat ConstantPointerNull (null) as constant offset 0 in the constraint
    instead of a variable. This slightly reduces the number of variables. I
    was not able to find a test case where this actually caused any changes.
