Log message:
	* common.opt: Add -fcheck-data-deps.
	* lambda-code.c (lambda_vector_lexico_pos): Moved ...
	* lambda.h (lambda_vector_lexico_pos): ... here.
	Make it static inline.
	* timevar.def (TV_CHECK_DATA_DEPS): New.
	* tree-data-ref.c (compute_subscript_distance,
	initialize_data_dependence_relation, compute_affine_dependence):
	Make static.
	(initialize_data_dependence_relation): Initialize DDR_CSYS,
	DDR_POLYHEDRON, DDR_OMEGA to NULL.  Initialize DDR_SIZE_VECT,
	DDR_DIST_VECT, DDR_DIR_VECT to allocated data.
	(analyze_subscript_affine_affine, analyze_overlapping_iterations):
	Correctly print the ending parenthesis in the dump file.
	(subscript_dependence_tester): Moved after
	build_classic_dist_vector and build_classic_dir_vector.
	Computes the classic representations.  Takes a new parameter.
	(build_classic_dist_vector): Add an extra check for ensuring that
	the output is a lexicographically vector.
	(build_classic_dist_vector, build_classic_dir_vector): Don't
	initialize the DDR_SIZE_VECT, DDR_DIST_VECT and DDR_DIR_VECT.
	(compute_affine_dependence): Add code for flag_check_data_deps.
	(compute_all_dependences): Move the call compute_subscript_distance
	to a lower level, in subscript_dependence_tester.
	(compute_data_dependences_for_loop): Move the calls
	build_classic_dist_vector and build_classic_dir_vector in
	subscript_dependence_tester.
	(tree_check_data_deps): New.
	* tree-data-ref.h (initialize_data_dependence_relation,
	compute_affine_dependence, compute_subscript_distance,
	build_classic_dist_vector): Remove extern declarations.
	* tree-flow.h (tree_check_data_deps): Declared.
	* tree-optimize.c: Schedule pass_check_data_deps.
	* tree-pass.h (pass_check_data_deps): Declared.
	* tree-ssa-loop.c (check_data_deps, gate_check_data_deps): New.
	(pass_check_data_deps): Instantiated.
	* doc/invoke.texi (fcheck-data-deps): Documented.
