This is intentional. In `clang/include/clang/`, `CMakeLists.txt` files are only used for TableGen targets. `clang/include/clang/Driver` had a single TableGen target, and this patch moves that input and its `CMakeLists.txt` to `clang/include/clang/Options`, so we switch to `add_subdirectory(Options)`.
