19663 also build a canonical type reference.
19664 (build_index_type): When we can't hash an index type (e.g.,
19665 because its maximum value is negative), the index type requires
19666 structural equality tests.
19667 (build_array_type): Build the canonical form of an array type.
19668 (build_function_type): Function types require structural equality,
19669 because they contain default arguments, attributes, etc.
