// NOTE: -fno-integrated-cc1 has been added to work around an ASAN failure
//       caused by in-process cc1 invocation. Clang InterfaceStubs is not the
//       culprit, but Clang Interface Stubs' Driver pipeline setup uncovers an
//       existing ASAN issue when invoking multiple normal cc1 jobs along with
//       multiple Clang Interface Stubs cc1 jobs together.
//       There is currently a discussion of this going on at:
//         https://reviews.llvm.org/D69825
