--- Comment #7 from Jeffrey A. Law <law at redhat dot com> ---
I think that in the past we'd just shove in any old hard register and it worked
because we considered the SCRATCH with 'X' as not conflicting with anything.
It's probably not ideal, but I wonder if LRA could do that for us too.
Alternately, maybe replace the scratch with const0_rtx.
