* bitmap.c (bitmap_last_set_bit): Rewrite to return the correct bit.

	* graphite.c (print_global_statistics): Use EDGE_COUNT instead
	of VEC_length.
	(print_graphite_scop_statistics): Likewise.
	* graphite-scop-detection.c (get_bb_type): Use single_succ_p.
	(print_graphite_scop_statistics): Use EDGE_COUNT, not VEC_length.
	(canonicalize_loop_closed_ssa): Use single_pred_p.

	* alias.c (reg_seen): Make this an sbitmap.
	(record_set, init_alias_analysis): Update.

	* tree-ssa-coalesce.c (ssa_conflicts_dump): Fix dumping.
