Revert "Implement nullPointerConstant() using a better API."
This reverts commit9148302a
(2019-08-22) which broke the pre-existing unit test for the matcher. Also revert commit518b2266
(Fix the nullPointerConstant() test to get bots back to green., 2019-08-22) which incorrectly changed the test to expect the broken behavior. Differential Revision: https://reviews.llvm.org/D96665
