22861 if the attributes are target-dependent and they differ, we need to
22862 use structural equality checks for this type.
22863 (build_qualified_type): A qualified type is not equivalent to its

22872 also build a canonical type reference.
22873 (build_index_type): When we can't hash an index type (e.g.,
22874 because its maximum value is negative), the index type requires
22875 structural equality tests.
22876 (build_array_type): Build the canonical form of an array type.
22877 (build_function_type): Function types require structural equality,
22878 because they contain default arguments, attributes, etc.
