Hi,
Current implementation requires that variables live outside of vect-loop 
satisfying LCSSA form, this patch relaxes the restriction.  It keeps the old 
behavior for LCSSA PHI node by replacing use of live var with result of that 
PHI; for other uses of live var, it simply replaces all uses outside loop with 
the newly computed var.

Thanks,

        * tree-vect-loop.c (vectorizable_live_operation): Support handling
        for live variable outside loop but not in lcssa form.

OK.
