TI_Arm_Clang_Compiler_1.3.0 not passing initial compiler test

It may be that the compiler needs more specific detections. I don’t see support for this compiler in CMake at the moment. Is there somewhere someone can get a copy of it to play around with to add support (not sure who could do it; depends on free time mostly). MRs welcome though. I don’t know if we have docs on how to add a new compiler or not.
