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

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

	* postreload-gcse.c (gate_handle_gcse2): Disable for functions
	optimized for speed.

	* 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.
