There are several reports of "unsupported unaligned store" or "can't determine
dependence between .."  The loops which report "unaligned store" vectorize OK
when taken in isolation.  
The reports of "can't determine dependence" appear to refer to the use of
multiple sections of the same array.  These sections cannot overlap unless
there is a subscript range violation.  Even if there were such a violation, it
could be taken care of by changing the order.
