--- Comment #8 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Adding some flag on the MASK_STORE or MASK_LOAD is not hard, it can be in
another argument, or some GF_*, whatever.  But I don't understand here what is
the difference between originally pointer based and array based access. 
Doesn't for non-masked stores or loads forwprop propagate array accesses into
pointer stores/loads anyway?
