29596 if the attributes are target-dependent and they differ, we need to
29597 use structural equality checks for this type.
29598 (build_qualified_type): A qualified type is not equivalent to its

29607 also build a canonical type reference.
29608 (build_index_type): When we can't hash an index type (e.g.,
29609 because its maximum value is negative), the index type requires
29610 structural equality tests.
29611 (build_array_type): Build the canonical form of an array type.
29612 (build_function_type): Function types require structural equality,
29613 because they contain default arguments, attributes, etc.
