15316 also build a canonical type reference.
15317 (build_index_type): When we can't hash an index type (e.g.,
15318 because its maximum value is negative), the index type requires
15319 structural equality tests.
15320 (build_array_type): Build the canonical form of an array type.
15321 (build_function_type): Function types require structural equality,
15322 because they contain default arguments, attributes, etc.
