9389 (build_index_type): When we can't hash an index type (e.g.,
9390 because its maximum value is negative), the index type requires
9391 structural equality tests.
9392 (build_array_type): Build the canonical form of an array type.
9393 (build_function_type): Function types require structural equality,
9394 because they contain default arguments, attributes, etc.

9396 (build_offset_type): Build the canonical offset type.
