16043 another type, the new type is its own canonical type.
16044 (build_variant_type_copy): When building a new type variant, we
16045 assume that it is equivalent to the original type.

16049 also build a canonical type reference.
16050 (build_index_type): When we can't hash an index type (e.g.,
16051 because its maximum value is negative), the index type requires
16052 structural equality tests.
16053 (build_array_type): Build the canonical form of an array type.
16054 (build_function_type): Function types require structural equality,
16055 because they contain default arguments, attributes, etc.
