	Replace TYPE_ARRAY_{UPPER,LOWER}_BOUND_TYPE by a bit if {un,}defined.
	* c-typeprint.c (c_type_print_varspec_suffix), m2-typeprint.c
	(m2_array), p-typeprint.c (pascal_type_print_varspec_prefix),
	valops.c (value_cast), varobj.c (c_number_of_children): Replace
	TYPE_ARRAY_UPPER_BOUND_TYPE compared to BOUND_CANNOT_BE_DETERMINED by
	TYPE_ARRAY_UPPER_BOUND_IS_UNDEFINED.
	* parse.c (follow_types): Use TYPE_ARRAY_UPPER_BOUND_IS_UNDEFINED.
	* f-valprint.c (f77_get_dynamic_upperbound): Replace with ...
	(f77_get_upperbound): ... this function handling now only
	TYPE_ARRAY_UPPER_BOUND_IS_UNDEFINED.
	(f77_get_dynamic_lowerbound): Replace with ...
	(f77_get_lowerbound): ... this function handling now only
	TYPE_ARRAY_LOWER_BOUND_IS_UNDEFINED.
	(f77_get_dynamic_length_of_aggregate, f77_create_arrayprint_offset_tbl):
	Update their callers.

	(BOUND_FETCH_OK, BOUND_FETCH_ERROR): Remove.
	* f-typeprint.c (f_type_print_varspec_suffix, f_type_print_base): Remove
	the lower_bound_was_default variable.  Update the
