[libc] Add more utility functions for the GPU
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`.
