Added files:
	gcc/testsuite/g++.dg/abi: empty8.C 

Log message:
	* class.c (check_field_decls): Remove empty_p parameter.  Instead,
	clear CLASSTYPE_EMPTY_P.
	(build_base_field): Likewise.
	(build_base_fields): Likewise.
	(check_bases_and_members): Likewise.
	(create_vtbl_ptr): Likewise.
	(layout_class_type): Likewise.  Ensure that empty classes have
	size zero when used as base classes in the 3.2 ABI.
	(finish_struct_1): Initialize CLASSTYPE_EMPTY_P and
	CLASSTYPE_NEARLY_EMPTY_P.  Adjust calls to avoid passing empty_p
	parameter.
	(is_empty_class): Correct definition when using post-3.2 ABI.
	* cp-tree.h (lang_type_class): Add empty_p.
	(CLASSTYPE_EMPTY_P): New macro.
