This patch adds extra intrinsics for the GPU. Some of these are unused for now but will be used later. We use these currently to update the `RPC` handling. Currently, every thread can update the RPC client, which isn't correct. This patch adds code neccesary to allow a single thread to perfrom the write while the others wait. Feedback is welcome for the naming of these functions. I'm copying the OpenMP nomenclature where we call an AMD `wavefront` or NVIDIA `warp` a `lane`.
