It looks like the clang driver just blindly adds these directories to the list of include paths, regardless of whether they exist or not. So with the current test, they don't need to exist (but maybe it would be good to create such empty directories to make the test a bit more correct, in case the driver is modified to not add nonexistent directories blindly).

FYI @maharmstone the test needs to be rebased to fit on top of current git, after rG897c86dec5af2780d443edd852aa5911e2650ec6 <https://reviews.llvm.org/rG897c86dec5af2780d443edd852aa5911e2650ec6>.
