re PR ipa/65005 (FAIL: c-c++-common/torture/builtin-arith-overflow-12.c)

	PR ipa/65005
	* ipa-visibility.c (cgraph_node::non_local_p): Turn into static
	function.
	* symtab.c (symtab_node::verify_base): Remove check that non-definitions
	have no comdat group.
	* lto-cgraph.c (lto_output_node): Always output thunk and alias info.
	(lto_output_varpool_node): Always output alias info.
	(output_refs): Output refs of boundary aliases, too.
	(compute_ltrans_boundary): Add alias and thunk target into boundaries.
	(output_symtab): Output call eges in thunks in boundary.
	(get_alias_symbol): Remove.
	(input_node, input_varpool_node): Do not special case weakrefs.
	* ipa.c (symbol_table::remove_unreachable_nodes): Do not remove
	alias and thunks targets in the boundary; do not take removed symbols
	from their comdat groups.
	* cgraph.c (cgraph_node::local_info): Look through aliases and thunks.
	(cgraph_node::global_info): Remove.
	(cgraph_node::rtl_info): Look through aliases and thunks.
	* cgrpah.h (global_info): Remove.
	(non_local_p): Remove.
