* 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.
