30433 if the attributes are target-dependent and they differ, we need to
30434 use structural equality checks for this type.
30435 (build_qualified_type): A qualified type is not equivalent to its

30444 also build a canonical type reference.
30445 (build_index_type): When we can't hash an index type (e.g.,
30446 because its maximum value is negative), the index type requires
30447 structural equality tests.
30448 (build_array_type): Build the canonical form of an array type.
30449 (build_function_type): Function types require structural equality,
30450 because they contain default arguments, attributes, etc.
