	exist and are objects. Remove checks for pointer.
	* tree-vectorizer.c (vect_create_addr_base_for_vector_ref): Use
	STMT_VINFO_VECT_DR_BASE_ADDRESS instead of DR_BASE_NAME.
	(vect_create_data_ref_ptr): Likewise.
	(vect_base_addr_differ_p): New function.
	(vect_analyze_data_ref_dependence): Call vect_base_addr_differ_p.
	(vect_analyze_pointer_ref_access): Add output parameter - ptr_init.
	Don't set the DR_BASE_NAME field of data-ref.
	(vect_get_memtag_and_dr): Use ptr_init instead of DR_BASE_NAME.
