30887 also build a canonical type reference.
30888 (build_index_type): When we can't hash an index type (e.g.,
30889 because its maximum value is negative), the index type requires
30890 structural equality tests.
30891 (build_array_type): Build the canonical form of an array type.
30892 (build_function_type): Function types require structural equality,
30893 because they contain default arguments, attributes, etc.
