More global trees.

	* cp-tree.h (enum cp_tree_index): Add CPTI_GLOBAL,
	CPTI_GLOBAL_TYPE, CPTI_GLOBAL_IDENTIFIER, CPTI_ANON_IDENTIFIER,
	CPTI_INIT_LIST_IDENTIFIER.
	(global_namespace, global_type_node, global_identifier)
	anon_identifier, init_list_identifier): New.
	* decl.c (global_type_node, global_scope_name): Delete.
	(initialize_predefined_identifiers): Add new identifiers.
	(cxx_init_decl_processing): Adjust.
	* name-lookup.h (global_namespace, global_type_node): Delete.
	* name-lookup.c (global_namespace, anonymous_namespace_name)
	get_anonymous_namespace_name): Delete.
	(namespace_scope_ht_size, begin_scope, pushtag_1)
	push_namespace): Adjust,
	* call.c (type_has_extended_temps): Use init_list_identifier.
	* pt.c (listify): Likewise.
