Log message:
	2004-11-29  Daniel Berlin  <dberlin@dberlin.org>
	
	* tree-data-ref.c (dependence_stats): New structure.
	(analyze_indirect_ref): New function.
	(analyze_ziv_subscript): Track ziv tests using dependence_stats.
	(get_number_of_iters_for_loop): New function.
	Replace repeated idiom to get number of real/estimated iterations
	in loop with this function.
	(analyze_siv_subscript_cst_affine): Track siv stats using
	dependence_stats.
	No dependence exists if first overlap is outside of the loop.
	(analyze_subscript_affine_affine): No dependence exists if first
	overlap of either variable is outside of the loop.
	(analyze_siv_subscript): Track siv stats using dependence_stats.
	(analyze_miv_subscript): Ditto for miv.
	(analyze_overlapping_iterations): Track total number of tests
	using dependence_stats.
	(compute_affine_dependence): Print out failing reference if affine
	test is unusable.
	(find_data_references_in_loop): Rewrite to handle indirect_ref as
	well using analyze_indirect_ref.
	(compute_data_dependences_for_loop): Initialize stats structure,
	print out stats if request.
