Log message:
	http://gcc.gnu.org/ml/gcc-patches/2003-07/msg00197.html
	* ra-build.c (determine_web_costs): Use copy_cost instead assuming
	memory move cost or constant cost.  Adjust heuristics to deal with
	spill temps and zero frequencies.  Penalize webs used in compares.
	(select_regclass): Reorder loops to first go over all full webs,
	and fill subwebs from them separately.  Accept empty usable regs
	for special webs.
	* ra-colorize.c (enough_free_p): New.
	(non_conflicting_for_combine): New.
	(sort_and_combine_web_pairs): Call both.
	(aggressive_coalesce, aggressive_coalesce_fast, extended_coalesce,
	extended_coalesce_2, check_uncoalesced_moves): Ditto.
	* ra-rewrite.c (spill_coalescing): Call non_conflicting_for_combine.
	(spill_prop_savings): Ditto.
	* ra.h (non_conflicting_for_combine): Declare.
