Long term I think we should do a new autoinc pass.  Currently
what we have is split between flow and regmove.

It would also be nice if it was able to interact with the
scheduler.  A more aggressive autoinc pass can constrain the
scheduler too much and reduce overall performance.  This is
especially visible on ia64.
