9847 (build_index_type): When we can't hash an index type (e.g.,
9848 because its maximum value is negative), the index type requires
9849 structural equality tests.
9850 (build_array_type): Build the canonical form of an array type.
9851 (build_function_type): Function types require structural equality,
9852 because they contain default arguments, attributes, etc.
