	gcc            : ChangeLog.killloop lambda-code.c lambda.h

Log message:
	* lambda-code.c (lambda_transform_legal_p): Use DDR_NUM_DIST_VECTS
	for testing whether the data_dependence_relation contains distance
	vectors.  Iterate over all distance vectors of the ddr.
	* lambda.h: Define a vec of lambda_vector pointers.
	* tree-data-ref.c (dump_data_dependence_relation,
	dump_data_dependence_direction): Iterate over all distance and
	direction vectors of the ddr.
	(initialize_data_dependence_relation): Initialize DDR_DIR_VECTS and
	DDR_DIST_VECTS.
	(build_classic_dist_vector, build_classic_dir_vector): Push a set
	of distance/direction vectors instead of a single one.
	* tree-data-ref.h (dir_vects, dist_vects): Replace dir/dist
	lambda_vectors with a vec of lambda_vectors.
	(DDR_DIR_VECT, DDR_DIST_VECT): Redefined as operations on vec.
	(DDR_DIR_VECTS, DDR_DIST_VECTS, DDR_NUM_DIR_VECTS,
	DDR_NUM_DIST_VECTS): New.
	* tree-loop-linear.c (gather_interchange_stats): Test for the
	existence of distance vectors only after having checked that there
	is a dependence.  Iterate over all distance vectors of the ddr.
	(linear_transform_loops): Use dump_data_dependence_relation.
	* tree-vect-analyze.c (vect_analyze_data_ref_dependence): Test for
	distance vectors using DDR_NUM_DIST_VECTS.  Iterate over all the
	distance vectors of the ddr.
