[CUDA] Added rudimentary support for CUDA-9 and sm_70.
For now CUDA-9 is not included in the list of CUDA versions clang searches for, so the path to CUDA-9 must be explicitly passed via --cuda-path=. On LLVM side NVPTX added sm_70 GPU type which bumps required PTX version to 6.0, but otherwise is equivalent to sm_62 at the moment.
