Log message:
	* tree-data-ref.c (base_addr_differ_p): Check parameters.
	(analyze_offset_expr): Remove redundant convert.
	(get_ptr_offset): Change in function parameter - alignment in bytes
	instead of type.
	(address_analysis): New parameter - boolean flag to determine the
	analysis mode. Change in parameter - alignment in bytes instead of
	type. Call object_analysis with additional parameter. Use alignment
	in bytes and call get_ptr_offset with different parameter.
	(object_analysis):  New parameter - boolean flag to determine the
	analysis mode. Change in parameter - alignment in bytes instead of type.
	Return after dr creation if the flag is false. Use alignment in bytes
	instead of alignment type.
	(create_data_ref):  New parameter - boolean flag to determine the
	analysis mode. Change in parameter - alignment in bytes instead of type.
	Call object_analysis with new parameters. Fix printings.
	(initialize_data_dependence_relation): Call base_addr_differ_p if
	possible.
	(compute_all_dependences): Skip read-read dependences.
	(find_data_references_in_loop): New parameters - boolean flag to
	determine the analysis mode and required alignment in bytes. Call
	create_data_ref.
	(compute_data_dependences_for_loop): New parameters - boolean flag to
	determine the analysis mode and required alignment in bytes. Call
	find_data_references_in_loop with new parameters.
	
	* tree-data-ref.h: New parameters in functions
	find_data_references_in_loop and compute_data_dependences_for_loop.
	Remove (make static) create_data_ref and base_addr_differ_p.
	
	* tree-loop-linear.c (linear_transform_loops): Call
	compute_data_dependences_for_loop with new parameters.
	
	* tree-ssa-loop-niter.c (estimate_numbers_of_iterations_loop): Call
	find_data_references_in_loop with new parameters.
	
	* tree-vect-analyze.c (vect_build_dist_vector): Remove.
	(vect_analyze_data_ref_dependence): Use ddr fields set previously.
	Compute loop depth for use of distance vector. Fix printings.
	(vect_analyze_data_ref_dependences): Go through ddrs instead of
	data-refs.
	(vect_compute_data_ref_alignment): All data-refs are now stored in one
	varray, and loads and stores are not separated.
	(vect_update_misalignment_for_peel, vect_verify_datarefs_alignment,
	vect_enhance_data_refs_alignment,  vect_analyze_data_ref_accesses):
	Likewise.
	(vect_analyze_data_refs): Fix comment. Call
	compute_data_dependences_for_loop to find and analyze data-refs in the
	loop.
	
	* tree-vect-transform.c (vect_update_inits_of_drs): All data-refs are
	now stored in one varray, and loads and stores are not separated.
	
	* tree-vectorizer.c (new_loop_vec_info): Initialize data-refs and ddr
	structures (varray).
	(destroy_loop_vec_info): Clear data-refs and ddr structures (varray).
	
	* tree-vectorizer.h (struct _loop_vec_inf): All data-refs are now
	stored in one varray, datarefs, and loads and stores are not separated.
	New field, ddrs. Macros for new fields.
