	* cgraphunit.c (cgraph_node::finalize_function): Set definition
	before notice_global_symbol.
	(varpool_node::finalize_decl): Likewise.
	* varasm.c (default_binds_local_p_2): Rename from
	default_binds_local_p_1, add weak_dominate argument.  Use direct
	returns instead of assigning to local variable.  Unify varpool and
	cgraph paths via symtab_node.  Reject undef weak variables before
	testing visibility.  Reorder tests for simplicity.
	(default_binds_local_p): Use default_binds_local_p_2.
	(default_binds_local_p_1): Likewise.
	(decl_binds_to_current_def_p): Unify varpool and cgraph paths
	via symtab_node.
	(default_elf_asm_output_external): Emit visibility when specified.
