AFAIK there's already handling for `call-graph-profile` which can inform the linker of the call-graph, so we could potentially just walk that graph, find the diameter of the register usage and then emit it in the final HSA metadata. There would still be the issue of LDS usage, but we could probably just state that LDS used by a kernel outside the current TU doesn't work for starters.
