12405 if the attributes are target-dependent and they differ, we need to

12407 (build_qualified_type): A qualified type is not equivalent to its

12416 also build a canonical type reference.
12417 (build_index_type): When we can't hash an index type (e.g.,
12418 because its maximum value is negative), the index type requires
12419 structural equality tests.
12420 (build_array_type): Build the canonical form of an array type.
12421 (build_function_type): Function types require structural equality,
12422 because they contain default arguments, attributes, etc.
