30428 if the attributes are target-dependent and they differ, we need to
30429 use structural equality checks for this type.
30430 (build_qualified_type): A qualified type is not equivalent to its

30432 (build_distinct_type_copy): When building a distinct type from

30439 also build a canonical type reference.
30440 (build_index_type): When we can't hash an index type (e.g.,
30441 because its maximum value is negative), the index type requires
30442 structural equality tests.
30443 (build_array_type): Build the canonical form of an array type.
30444 (build_function_type): Function types require structural equality,
30445 because they contain default arguments, attributes, etc.
