* ieee.c (struct ieee_var): Remove variable field. Add kind

	field, and define some enum constants for it.
	(parse_ieee_ty): Set kind field of variable for 'x' and 'X' types.
	(parse_ieee_atn): Make an indirect slot for an external variable,
	although we otherwise don't record it.  Set kind field rather than
	variable field of pvar.
	(ieee_read_cxx_class): Try to get the type of a static member.
	(ieee_read_reference): Check kind field rather than variable
	field.
