4776 if the attributes are target-dependent and they differ, we need to
4777 use structural equality checks for this type.
4778 (build_qualified_type): A qualified type is not equivalent to its
4779 unqualified variant; set the canonical type appropriately.
4780 (build_distinct_type_copy): When building a distinct type from
4781 another type, the new type is its own canonical type.
4782 (build_variant_type_copy): When building a new type variant, we
4783 assume that it is equivalent to the original type.
4784 (build_pointer_type_for_mode): When building a pointer type, also
4785 build a canonical type pointer.
4786 (build_reference_type_for_mode): When building a reference type,
4787 also build a canonical type reference.
4788 (build_index_type): When we can't hash an index type (e.g.,
4789 because its maximum value is negative), the index type requires
4790 structural equality tests.
4791 (build_array_type): Build the canonical form of an array type.
4792 (build_function_type): Function types require structural equality,
4793 because they contain default arguments, attributes, etc.
4794 (build_method_type_directly): Ditto for method types.
4795 (build_offset_type): Build the canonical offset type.
4796 (build_complex_type): Build the canonical vector type.
