Discussed IRL.  We're not breaking anyone who's not already broken -- if you currently have "__device__ __attribute__((used)) static int foo()", that's just not going to compile for you without this patch.  With this patch, at least this will work for some people; we can always add this stub function later if we want (I have concerns about potentially surprising performance implications, but we can postpone worrying about that).
