9722 if the attributes are target-dependent and they differ, we need to
9723 use structural equality checks for this type.
9724 (build_qualified_type): A qualified type is not equivalent to its
9725 unqualified variant; set the canonical type appropriately.
9726 (build_distinct_type_copy): When building a distinct type from
9727 another type, the new type is its own canonical type.
9728 (build_variant_type_copy): When building a new type variant, we
9729 assume that it is equivalent to the original type.
9730 (build_pointer_type_for_mode): When building a pointer type, also
9731 build a canonical type pointer.
9732 (build_reference_type_for_mode): When building a reference type,
9733 also build a canonical type reference.
9734 (build_index_type): When we can't hash an index type (e.g.,
9735 because its maximum value is negative), the index type requires
9736 structural equality tests.
9737 (build_array_type): Build the canonical form of an array type.
9738 (build_function_type): Function types require structural equality,
9739 because they contain default arguments, attributes, etc.
9740 (build_method_type_directly): Ditto for method types.
9741 (build_offset_type): Build the canonical offset type.
9742 (build_complex_type): Build the canonical vector type.
