I don't see any reason why a generic calling convention would not work.  We
could do something like cl_device/cl_kernel.  I hate to introduce OpenCL
terms into a back-end where OpenCL is just one consumer, but it does map
cleanly to the architecture model.  Or perhaps something more generic like
gpu_device/gpu_global.
