	PR c++/11226, PR c++/9629, PR c++/9688, PR c++/8890:
	* valops.c (search_struct_field): Compute nbases after calling
	CHECK_TYPEDEF.
	(check_field): Call CHECK_TYPEDEF.
	* cp-valprint.c (cp_print_value): Pass correct address to
	baseclass_offset.  Fix check for virtual base past the end of the
	object.  Don't offset address passed to cp_print_value_fields or
	apply_val_pretty_printer.
	(cp_print_value_fields): Fix call to val_print.
	(cp_print_value_fields_rtti): New function.
	* c-valprint.c (c_val_print): Use cp_print_value_fields_rtti.
	* p-valprint.c (pascal_object_print_value_fields): Fix call to
	val_print.
	* python/py-prettyprint.c (apply_val_pretty_printer): Add embedded
	offset to address.
	* language.h (struct language_defn) <la_val_print>: Document.
	* c-lang.h (cp_print_value_fields_rtti): Declare.
