I don't plan to land this; I wrote it in case it comes up in code review.  llvm's codegen will `report_fatal_error` for garbage sysregs.  If it comes up again in the future, this phab review will still exist for reference, but I suggest we only add what's needed in that case, not all possible sysregs since most make sense in this context I suspect.
