	* cp-valprint.c (cp_print_value_fields): Check valprint_check_validity
	for TYPE_VPTR_FIELDNO.
	* valprint.c (valprint_check_validity): Make it global, move the
	function comment ...
	* value.h (valprint_check_validity): ... to this new declaration.

	(collect globals: print object on: print derived_partial)
	(collect globals: print object on: print derived_whole)
	(collect globals: print object off: print derived_partial)
	(collect globals: print object off: print derived_whole): Update
	expected output.
