Cleanup offload datatransfer There are 3 steps to run code on a GPU: Copy data from the host to the device, launch the kernel, and move it back. At the moment, we have a single variable describing the memory handling to do in each step, but that makes it hard for LLVM's opt pass to understand what's going on. We therefore split it into three variables, each only including the bits relevant for the corresponding stage. cc @jdoerfert @kevinsala r? compiler
