	* tree-data-ref.h (build_rdg): Drop all parameters but loop.
	* tree-data-ref.c (create_rdg_vertices): Collect all data
	references, signal failure to the caller, use data-ref API.
	(build_rdg): Compute data references only once.  Maintain
	lifetime of data references and data dependences from within
	RDG.
	(free_rdg): Free dependence relations.
	* tree-loop-distribution.c (rdg_flag_uses): Drop weird code
	inventing extra dependences.
	(distribute_loop): Update for RDG API changes.
