From-SVN: r258834

This PR is another regression caused by the removal of the simple_iv
check in dr_analyze_innermost for BB analysis.  Without splitting out
the step, we weren't able to find an underlying object whose alignment
could be increased.

As with PR81635, I think the simple_iv was only handling one special
case of something that ought to be more general.  The more general
thing here is that if the address can be analysed as a scalar
evolution, and if all updates preserve alignment N, it's possible
to align the address to N by increasing the alignment of the base
object to N.  That applies also to outer loops, and to both loop
and BB analysis.

I wasn't sure where the new functions ought to live, but tree-data-ref.c
seemed OK since (a) that already does scev analysis on addresses and
(b) you'd want to use dr_analyze_innermost first if you were analysing
a reference.
