	gcc            : ChangeLog.autovect tree-data-ref.c 
	                 tree-scalar-evolution.c 

Log message:
	* tree-data-ref.c (subscript_dependence_tester): Count only once
	dependent relations instead of incrementing num_dependence_dependent
	for each subscript.
	* tree-scalar-evolution.c (add_to_evolution): Don't handle REAL_CST.
	(number_of_iterations_for_all_loops): Count the number of loops for
	which there is an estimation of the number of iterations.
	(number_of_iterations_for_all_loops): Print nb_estimated_loops.
	(chrec_stats): Add nb_other.
	(reset_chrecs_counters): Initialize to zero nb_other.
	(dump_chrecs_stats): Dump nb_other, the number of compound
	expressions.
	(gather_chrec_stats): Count the number of undetermined chrecs before
	the classification.  On the default case, increment nb_other.
	(analyze_scalar_evolution_for_all_loop_phi_nodes): Avoid iterating
	over the loop phis, because some of them could be removed
	during the analysis.  Record the phi nodes that have to be analyzed
	in a vector of trees.
