19639 also build a canonical type reference.
19640 (build_index_type): When we can't hash an index type (e.g.,
19641 because its maximum value is negative), the index type requires
19642 structural equality tests.
19643 (build_array_type): Build the canonical form of an array type.
19644 (build_function_type): Function types require structural equality,
19645 because they contain default arguments, attributes, etc.
