11606 also build a canonical type reference.
11607 (build_index_type): When we can't hash an index type (e.g.,
11608 because its maximum value is negative), the index type requires
11609 structural equality tests.
11610 (build_array_type): Build the canonical form of an array type.
11611 (build_function_type): Function types require structural equality,
11612 because they contain default arguments, attributes, etc.
