Puyan Lotfi e782192d5e [clang][IFS][test][NFC] Tightening up clang-ifs tests to use -cc1 more often.
Unless the test is explicitly testing a driver feature if clang
interface stubs I have changed the tests to use %clang_cc1. This should
make some changes I plan to make to the driver job pipeline cause fewer
test changes and breakages.
