* cgraph.c (cgraph_add_thunk): Create real function node instead

	of alias node; finalize it and mark needed/reachale; arrange visibility
	to be right and add it into the corresponding same comdat group list.
	(dump_cgraph_node): Dump thunks.
	* cgraph.h (cgraph_first_defined_function, cgraph_next_defined_function,
	cgraph_function_with_gimple_body_p, cgraph_first_function_with_gimple_body,
	cgraph_next_function_with_gimple_body): New functions.
	(FOR_EACH_FUNCTION_WITH_GIMPLE_BODY, FOR_EACH_DEFINED_FUNCTION):
	New macros.
	* ipa-cp.c (ipcp_need_redirect_p): Thunks can't be redirected.
	(ipcp_generate_summary): Use FOR_EACH_FUNCTION_WITH_GIMPLE_BODY.
	* cgraphunit.c (cgraph_finalize_function): Only look into possible
	devirtualization when optimizing.
	(verify_cgraph_node): Verify thunks.
	(cgraph_analyze_function): Analyze thunks.
	(cgraph_mark_functions_to_output): Output thunks only in combination
	with function they are assigned to.
	(assemble_thunk): Turn thunk into non-thunk; don't try to turn
	alias into normal node.
	(assemble_thunks): New functoin.
	(cgraph_expand_function): Use it.
	* lto-cgraph.c (lto_output_node): Stream thunks.
	(input_overwrite_node): Stream in thunks.
	* ipa-pure-const.c (analyze_function): Thunks do nothing interesting.
	* lto-streamer-out.c (lto_output): Do not try to output thunk's body.
	* ipa-inline.c (inline_small_functions): Use FOR_EACH_DEFINED_FUNCTION.
	* ipa-inline-analysis.c (compute_inline_parameters): "Analyze" thunks.
	(inline_analyze_function): Do not care about thunk jump functions.
	(inline_generate_summary):Use FOR_EACH_DEFINED_FUNCTION.
	* ipa-prop.c (ipa_prop_write_jump_functions): Use cgraph_function_with_gimple_body_p.
	* passes.c (do_per_function_toporder): Use cgraph_function_with_gimple_body_p.
	(execute_one_pass);Use FOR_EACH_FUNCTION_WITH_GIMPLE_BODY.
	(ipa_write_summaries): Use cgraph_function_with_gimple_body_p.
	(function_called_by_processed_nodes_p): Likewise.
	* lto.c (lto_materialize_function): Use cgraph_function_with_gimple_body_p.
	(add_cgraph_node_to_partition): Do not re-add items to partition; handle thunks.
	(add_varpool_node_to_partition): Do not re-add items to partition.
