11154 also build a canonical type reference.
11155 (build_index_type): When we can't hash an index type (e.g.,
11156 because its maximum value is negative), the index type requires
11157 structural equality tests.
11158 (build_array_type): Build the canonical form of an array type.
11159 (build_function_type): Function types require structural equality,
11160 because they contain default arguments, attributes, etc.
