Actually the code in var-tracking.c does handle the situation that a reg
contains multiple decls.  Or better it tries to.  If there weren't an
obvious bug in clobber_variable_part().  With that fixed the looping doesn't
occur anymore, as the OUT set now doesn't depend on the order of IN anymore,
as it should be:

                    }
