28725 own canonical type.
28726 (build_type_attribute_qual_variant): When building an attribute

28728 if the attributes are target-dependent and they differ, we need to
28729 use structural equality checks for this type.
28730 (build_qualified_type): A qualified type is not equivalent to its
28731 unqualified variant; set the canonical type appropriately.

28733 another type, the new type is its own canonical type.

28738 (build_reference_type_for_mode): When building a reference type,
28739 also build a canonical type reference.
28740 (build_index_type): When we can't hash an index type (e.g.,
28741 because its maximum value is negative), the index type requires
28742 structural equality tests.
28743 (build_array_type): Build the canonical form of an array type.
28744 (build_function_type): Function types require structural equality,
28745 because they contain default arguments, attributes, etc.
28746 (build_method_type_directly): Ditto for method types.
28747 (build_offset_type): Build the canonical offset type.
