14053 if the attributes are target-dependent and they differ, we need to

14064 also build a canonical type reference.
14065 (build_index_type): When we can't hash an index type (e.g.,
14066 because its maximum value is negative), the index type requires
14067 structural equality tests.
14068 (build_array_type): Build the canonical form of an array type.
14069 (build_function_type): Function types require structural equality,
14070 because they contain default arguments, attributes, etc.
