31363 use structural equality checks for this type.
31364 (build_qualified_type): A qualified type is not equivalent to its

31373 also build a canonical type reference.
31374 (build_index_type): When we can't hash an index type (e.g.,
31375 because its maximum value is negative), the index type requires
31376 structural equality tests.
31377 (build_array_type): Build the canonical form of an array type.
31378 (build_function_type): Function types require structural equality,
31379 because they contain default arguments, attributes, etc.
