        PR tree-opt/32527
        * tree-affine.h (aff_tree): The type of rest is sizetype for types
        of pointers.
        * tree-affine.c (aff_combination_scale): If type is a pointer type,
        use sizetype for rest.
        (aff_combination_add_elt): Likewise. Don't specialize pointer types.
        (aff_combination_convert): Don't convert rest for pointer types.
