 166         own canonical type.

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

 182         because its maximum value is negative), the index type requires
 183         structural equality tests.
 184         (build_array_type): Build the canonical form of an array type.
 185         (build_function_type): Function types require structural equality,

 187         (build_method_type_directly): Ditto for method types.
 188         (build_offset_type): Build the canonical offset type.
