* parse.c (parse_interface): Silence uninitialized var warning.

	* postreload-gcse.c (gate_handle_gcse2): Disable for functions
	optimized for speed.
	* final.c (compute_alignments): Use optimize_bb_for_size_p.
	* tree-call-cdce.c (gate_call_cdce): Use optimize_function_for_speed_p.
	* opts.c (flag_predictive_commoning_set, flag_unswitch_loops_set,
	flag_gcse_after_reload_set): New static vars.
	(common_handle_option): Enable those flags for profile-use.
	(decode_options): Remove optimize_size flags that are handled
	on higher granuality.
	* tree-vectorizer.c (vectorize_loops): Use
	optimize_loop_nest_for_speed_p.
	* tree-ssa-pre.c (do_pre): Use optimize_function_for_speed_p.
	* tree-predcom.c (tree_predictive_commoning): Use
	optimize_loop_for_speed_p.
	* varasm.c (assemble_start_function): Use optimize_function_for_speed_p.
	* bb-reorder.c (rest_of_handle_reorder_blocks): Likewise.
	* predict.c (optimize_loop_for_speed_p): Fix walk.
