5842 (build_index_type): When we can't hash an index type (e.g.,
5843 because its maximum value is negative), the index type requires
5844 structural equality tests.
5845 (build_array_type): Build the canonical form of an array type.
5846 (build_function_type): Function types require structural equality,
5847 because they contain default arguments, attributes, etc.
