Split the libclc subproject out of the clang recipe and into a dedicated libclc recipe. This is useful because libclc is the OpenCL runtime library and as such isn't target-specific and needs a native clang to build, not a target libllvm. Verified that nothing is dropped by adding clang and libclc to an image and verifying that the file list is the same before and after this change. We need to patch the libclc CMakeLists to allow it to use an out-of-tree prepare_builtins binary, discussion is ongoing with upstream to resolve this properly.
