re PR tree-optimization/31358 (IV-OPTs produces a weird MEM_REF)

PR tree-optimization/31358
* tree-ssa-loop-manip.c (create_iv): Call force_gimple_operand for
the step with a NULL_TREE.
* tree-ssa-loop-ivopts.c (find_bivs): Convert the step
to sizetype if type is a pointer type.
(add_candidate_1): Don't convert the base and step to
the generic type if the orginal type is a pointer type.
(add_iv_value_candidates): Use sizetype for the step
if type is a pointer type.
(cand_value_at): Likewise.
* tree-ssa-address.c (add_to_parts): Use POINTER_PLUS_EXPR
for pointer types.
* tree-affine.c (tree_to_aff_combination <POINTER_PLUS_EXPR>):
Don't convert the tem affine to the type.
(add_elt_to_tree): Use sizetype for the step if a pointer.
Use POINTER_PLUS_EXPR for pointers.
(aff_combination_to_tree): Use sizetype for the step if a
pointer.
