poly_int: aff_tree
This patch changes the type of aff_tree::offset from widest_int to
poly_widest_int and adjusts the function interfaces in the same way.

gcc/
* tree-affine.h (aff_tree::offset): Change from widest_int
to poly_widest_int.
(wide_int_ext_for_comb): Delete.
(aff_combination_const, aff_comb_cannot_overlap_p): Take the
constants as poly_widest_int rather than widest_int.
(aff_combination_constant_multiple_p): Return the multiplier
as a poly_widest_int.
(aff_combination_zero_p, aff_combination_singleton_var_p): Handle
polynomial offsets.
* tree-affine.c (wide_int_ext_for_comb): Make original widest_int
version static and add an overload for poly_widest_int.
(aff_combination_const, aff_combination_add_cst)
(wide_int_constant_multiple_p, aff_comb_cannot_overlap_p): Take
the constants as poly_widest_int rather than widest_int.
(tree_to_aff_combination): Generalize INTEGER_CST case to
poly_int_tree_p.
(aff_combination_to_tree): Track offsets as poly_widest_ints.
(aff_combination_add_product, aff_combination_mult): Handle
polynomial offsets.
(aff_combination_constant_multiple_p): Return the multiplier
as a poly_widest_int.
* tree-predcom.c (determine_offset): Return the offset as a
poly_widest_int.
(split_data_refs_to_components, suitable_component_p): Update
accordingly.
(valid_initializer_p): Update call to
aff_combination_constant_multiple_p.
* tree-ssa-address.c (addr_to_parts): Handle polynomial offsets.
* tree-ssa-loop-ivopts.c (get_address_cost_ainc): Take the step
as a poly_int64 rather than a HOST_WIDE_INT.
(get_address_cost): Handle polynomial offsets.
(iv_elimination_compare_lt): Likewise.
(rewrite_use_nonlinear_expr): Likewise.
