The patch implementing ia64 changes needed for the selective scheduler can be
found at http://gcc.gnu.org/ml/gcc-patches/2008-08/msg01669.html.  [The first
version of the patch with some summary is at
http://gcc.gnu.org/ml/gcc-patches/2008-06/msg00117.html.  What is changed from
that summary is that per Ian's suggestion we call compute_alignments from
machine_reorg manually instead of rearranging the pass sequence.] 

I was going to ping them, but HJ did that first.  It is important that we get
that in for 4.4, because otherwise selective scheduler will be non-functional
on ia64.  However, I presume reviewing the changes will take some time, so it
could make sense to fix this bug first.  The patch for the bug is simple, and
it is not a problem to revert it when committing the rest of sel-sched changes. 

On the sel-sched branch, I have restored the config/ia64/* files to be in line
with mainline before merge.  I will revert this on a branch in two-three days,
so that the sel-sched branch will contain a fully functional selective
scheduler on ia64.
