11265         own canonical type.

11280         (build_index_type): When we can't hash an index type (e.g.,
11281         because its maximum value is negative), the index type requires
11282         structural equality tests.
11283         (build_array_type): Build the canonical form of an array type.
11284         (build_function_type): Function types require structural equality,
