Summary: OpenMP has the ability to offload target regions to devices which may have different architectures. A new -fopenmp-target-arch flag is introduced to specify the device architecture. In this patch I use the new flag to specify the compute capability of the underlying NVIDIA architecture for the OpenMP offloading CUDA tool chain. Only a host-offloading test is provided since full device offloading capability will only be available when [[ https://reviews.llvm.org/D29654 | D29654 ]] lands.
