5727 (build_distinct_type_copy): When building a distinct type from
5728 another type, the new type is its own canonical type.
5729 (build_variant_type_copy): When building a new type variant, we
5730 assume that it is equivalent to the original type.

5732 build a canonical type pointer.

5734 also build a canonical type reference.
5735 (build_index_type): When we can't hash an index type (e.g.,
5736 because its maximum value is negative), the index type requires
5737 structural equality tests.
5738 (build_array_type): Build the canonical form of an array type.
5739 (build_function_type): Function types require structural equality,
5740 because they contain default arguments, attributes, etc.
