ipa-comdats.c: Remove optimize check from gate.

	* ipa-comdats.c: Remove optimize check from gate.
	* ipa-fnsummary.c (ipa_fn_summary_generate): do not generate summary
	for functions not optimized.
	(ipa_fn_summary_read): Skip optimize check.
	(ipa_fn_summary_write): Likewise.
	* ipa-inline-analysis.c (do_estimate_growth_1): Check that caller
	is optimized.
	* ipa-inline.c (can_inline_edge_p): Not optimized functions are
	uninlinable.
	(can_inline_edge_p): Check flag_pcc_struct_return for match.
	(check_callers): Give up on caller which is not optimized.
	(inline_small_functions): Likewise.
	(ipa_inline): Do not give up when not optimizing.
	* ipa-visbility.c (function_and_variable_visibility): Do not optimize
	away unoptimizes cdtors.
	(whole_program_function_and_variable_visibility): Do
	ipa_discover_readonly_nonaddressable_vars in LTO mode.
	* ipa.c (process_references): Do not check optimize.
	(symbol_table::remove_unreachable_nodes): Update optimize check.
	(set_writeonly_bit): Update optimize check.
	(pass_ipa_cdtor_merge::gate): Do not check optimize.
	(pass_ipa_single_use::gate): Remove.
