[CMake] Add missing set_output_directory after Takumi's change in r198205.

not LLVM's.

Xcode still has a few issues finding auxiliary tools and libraries in the
build folders. I'll fix those next.

CMake separate projects: finish output-directory changes.

Make sure clang-tblgen, clang++, and clang-cl get created in the Clang
binary build directory.
