--- Comment #9 from anlauf at gcc dot gnu.org ---
The loop can be vectorized if the final value of the 'saved' scalar can be
determined.
Some vectorizing compilers (Cray, NEC) offer directives (e.g. lstval/nolstval)
to control the evaluation of that scalar, and sometimes suggest to add that
directive in front of the loop.
I think the requirements for handling this are very similar to those for the
OpenMP lastprivate declaration.
