9398 (build_index_type): When we can't hash an index type (e.g.,
9399 because its maximum value is negative), the index type requires
9400 structural equality tests.
9401 (build_array_type): Build the canonical form of an array type.
9402 (build_function_type): Function types require structural equality,
9403 because they contain default arguments, attributes, etc.
