Those tests intentionally do not use update_cc_test_checks.py, because Clang without optimizations creates quite a lot redundant IR. The check lines in the test only check the relevant bits for lowering the builtins (where the arguments are coming from and which intrinsic is called). It is probably easiest to just follow the current scheme.
