17792 another type, the new type is its own canonical type.
17793 (build_variant_type_copy): When building a new type variant, we
17794 assume that it is equivalent to the original type.

17798 also build a canonical type reference.
17799 (build_index_type): When we can't hash an index type (e.g.,
17800 because its maximum value is negative), the index type requires
17801 structural equality tests.
17802 (build_array_type): Build the canonical form of an array type.
17803 (build_function_type): Function types require structural equality,
17804 because they contain default arguments, attributes, etc.
