	* tree-vectorizer.h (stmt_vec_info): Add vect_dr_base field.
	(STMT_VINFO_VECT_DR_BASE): Declare.
	(VECT_SMODULO): Declare.
	* tree-vectorizer.c (vect_compute_array_ref_alignment): New function.
	(vect_compute_array_base_alignment): New function.
	(vect_analyze_data_ref_access): Check array indices. Remove one
	dimensional arrays restriction.
	(vect_get_ptr_offset): New function.
	(vect_get_symbl_and_dr): New function.
	(vect_get_base_and_bit_offset): Support additional data refs. Renamed
	(former name vect_get_base_decl_and_bit_offset).
	(vect_create_index_for_array_ref): Removed.
	(vect_create_index_for_vector_ref): New function.
	(vect_create_addr_base_for_vector_ref): New function.
	(vect_create_data_ref): Handle additional data refs. Call
	vect_create_index_for_vector_ref and vect_create_addr_base_for_vector_ref.
	(vect_compute_data_ref_alignment): Support the changes. Call
	vect_get_base_and_bit_offset.
	(vect_analyze_data_refs): Call vect_get_symbl_and_dr. Support additional
	data refs. Store vect_dr_base.
	(vect_analyze_data_ref_accesses): Support nonconstant init.
	(new_stmt_vec_info): Initialize vect_dr_base field.
	(vect_is_simple_iv_evolution): Call initial_condition_in_loop_num.
	(get_vectype_for_scalar_type): Check for BLKmode.
	* tree-chrec.h (initial_condition_in_loop_num): Declare.
	* tree-chrec.c (initial_condition_in_loop_num): New function.
	(chrec_component_in_loop_num): New function.
	(evolution_part_in_loop_num): Call chrec_component_in_loop_num.
	* tree-data-ref.c (analyze_array_indexes): Change parameter (access_fns)
	to be pointer to varray_type.
