12895 also build a canonical type reference.
12896 (build_index_type): When we can't hash an index type (e.g.,
12897 because its maximum value is negative), the index type requires
12898 structural equality tests.
12899 (build_array_type): Build the canonical form of an array type.
12900 (build_function_type): Function types require structural equality,
12901 because they contain default arguments, attributes, etc.
