12418 if the attributes are target-dependent and they differ, we need to

12429 also build a canonical type reference.
12430 (build_index_type): When we can't hash an index type (e.g.,
12431 because its maximum value is negative), the index type requires
12432 structural equality tests.
12433 (build_array_type): Build the canonical form of an array type.
12434 (build_function_type): Function types require structural equality,
12435 because they contain default arguments, attributes, etc.
