CUDA/HIP program may be compiled with -fopenmp. In this case, -fopenmp is only passed to host compilation to take advantages of multi-threads computation. CUDA/HIP and OpenMP both use Sema::DeviceCallGraph to store functions to be analyzed and remove them once they decide the function is sure to be emitted. CUDA/HIP and OpenMP have different functions to determine if a function is sure to be emitted. To check host/device correctly for CUDA/HIP when -fopenmp is enabled, there needs a unified logic to determine whether a function is to be emitted. The logic needs to be aware of both CUDA and OpenMP logic. Differential Revision: https://reviews.llvm.org/D67837 llvm-svn: 374263
