28411         own canonical type.

28426         (build_index_type): When we can't hash an index type (e.g.,
28427         because its maximum value is negative), the index type requires
28428         structural equality tests.
28429         (build_array_type): Build the canonical form of an array type.
28430         (build_function_type): Function types require structural equality,
