* c-common.h (struct c_fileinfo): Comment moved here from cp-tree.h.

	(extract_interface_info): Delete prototype.
	* c-decl.c (extract_interface_info): Delete stub.
	* c-lex.c (get_fileinfo): Initialize file_info_tree here, if
	it's not already been done ...
	(init_c_lex): ... not here.
	(fe_file_change): Don't call extract_interface_info.
cp:
	* cp-tree.h (interface_only, interface_unknown): Delete declarations;
	comment explaining them moved to c-common.h.
	* lex.c (interface_only, interface_unknown, extract_interface_info):
	Delete definitions.
	(cxx_finish): Don't reset interface_unknown.
	(handle_pragma_interface): Don't set interface_only and
	interface_unknown; just the like-named fields in finfo.
	(handle_pragma_implementation): Adjust comment.
	* decl2.c (cp_finish_file): Don't reset interface_only and
	interface_unknown.
	* method.c (synthesize_method): Don't reset interface_unknown or
	call extract_interface_info.
	* pt.c (pop_tinst_level): Don't call extract_interface_info.
	* decl.c (start_cleanup_fn): Don't save or restore interface_only
	and interface_unknown.
	(make_rtl_for_nonlocal_decl): Call get_fileinfo on input_filename
	and use the result instead of the interface_only/interface_unknown
	globals.
	(start_preparsed_function): Likewise.
	* lex.c (cxx_make_type): Likewise.
	* semantics.c (begin_class_definition): Likewise.
	(expand_body): Don't call extract_interface_info.
