/// @assertion From the Constant-update-2018 Spec:
/// The operator [>>>] is now allowed in a potentially constant expression, and
/// it is valid in constant expression if its left and right operands are [int]
/// instances, and the operation doesn't throw. The [>>>] operator has not been
/// added to the [int] class yet, so unless the left-hand operand's static type
/// is [dynamic], the program will still be rejected. When the operator is added,
/// it should then also work in a constant expression.
/// @description Checks that arguments of [>>>] operator should be int.
/// @Issue 30886
