Here I disagree. IMHO simplifying any back end is a win, because it
lowers the threshold to "modernize it". For instance for HP-PA, I
would like to play with Bernd's new delay branch schedule model
(http://gcc.gnu.org/ml/gcc-patches/2011-05/msg00753.html) and that
will simply be a less daunting job if the back end is smaller. It will
also be easier to test.
