Log message:
	* tree-fold-const.h (chrec_merge_types): Move it...
	* tree-chrec.c (multiply_int, divide_int, add_int, substract_int,
	integer_divides_p, lcm, gcd, update_initial_condition_to_origin,
	remove_initial_condition, ): Removed.
	(evolution_function_in_loop_num): Renamed into
	hide_evolution_in_other_loops_than_loop.
	(hide_evolution_in_loop, hide_evolution_in_other_loops_than_loop): New.
	(chrec_merge_types): ... here.
	(chrec_merge): Answer chrec_top on EXPONENTIAL_CHREC.
	(ziv_subscript_p, siv_subscript_p, analyze_ziv_subscript,
	analyze_siv_subscript, analyze_siv_subscript_cst_affine,
	analyze_siv_subscript_affine_cst, analyze_siv_subscript_affine_affine,
	chrec_steps_divide_constant_p, analyze_miv_subscript,
	analyze_overlapping_iterations): Moved from here...
	* tree-chrec.h (evolution_function_in_loop_num): Rename declaration.
	(hide_evolution_in_other_loops_than_loop, hide_evolution_in_loop): New.
	(analyze_overlapping_iterations): No longer extern.
	
	* tree-data-ref.c (ziv_subscript_p, siv_subscript_p,
	analyze_ziv_subscript,
	analyze_siv_subscript, analyze_siv_subscript_cst_affine,
	analyze_siv_subscript_affine_cst, analyze_siv_subscript_affine_affine,

	analyze_overlapping_iterations): ... there.
	(initialize_data_dependence_relation,
	access_functions_are_affine_or_constant_p): Moved down.
	(compute_all_dependences): Moved down.  Now is static.
	(build_classic_dir_vector): New.
	(build_classic_dist_vector):
	(find_data_references): Renamed find_data_references_in_loop.
	Now is static.
	(compute_data_dependences_for_loop): New.
	(analyze_all_data_dependences): Use compute_data_dependences_for_loop.
	* tree-data-ref.h (dd_info_available): Don't declare it extern.
	
	* tree-scalar-evolution.c (dd_info_available): Declare static.
	(select_outer_and_current_evolutions): Removed.
	(stats_*): Move the static variables in the chrec_stats structure.
	(chrec_stats): New structure.
	(first_iteration_non_satisfying_1): In the multivariate case,
	don't forget that the outer loops can change the number of iterations.
	(cannot_analyze_loop_nb_iterations_yet): Removed.
	(follow_ssa_edge_inner_loop_phi): Refine the case where the
	evolution of the inner loop is symbolic.
	(number_of_iterations_in_loop): Factor the end of the cases.
	
	* tree-dg.c (classic_dist, classic_dir): Declared static.
	(dg_delete_graph): Delete the classic_dist and classic_dir.
	(dg_create_graph): Adapt to use compute_data_dependences_for_loop.
	(gate_ddg, gate_delete_ddg, pass_ddg, pass_delete_ddg): Moved in
	tree-scalar-evolution.c.
	* tree-dg.h (dg_create_graph): Pass in struct loops.
