3613 (build_index_type): When we can't hash an index type (e.g.,
3614 because its maximum value is negative), the index type requires
3615 structural equality tests.
3616 (build_array_type): Build the canonical form of an array type.
3617 (build_function_type): Function types require structural equality,
3618 because they contain default arguments, attributes, etc.
