2007-10-25  Richard Guenther  <rguenther@suse.de>

	* tree-flow.h (mem_sym_stats): Remove.
	(dump_mem_sym_stats_for_var): Declare.
	* tree-dfa.c (dump_variable): Call dump_mem_sym_stats_for_var.
	(mem_sym_stats): Move ...
	* tree-ssa-alias.c (mem_sym_stats): ... here and make it static.
	(mem_sym_score): Rename from ...
	(pscore): ... this.  Remove.
	(dump_mem_sym_stats_for_var): New function.  Dump the score, but
	not the frequencies.
	(compare_mp_info_entries): Make sort stable by disambiguating
	on DECL_UID.
