I'm afraid the upstreaming of CMSE has stalled, and this is not all that would be needed to get it working. This adds some header files and clang builtins, the selection of them in the backend isn't yet present, hence the error you are seeing. There are more patches to follow around lowering intrinsics and clearing registers correctly.
