the class UpperBoundTransfer method propagateToOperands.

 * multiplication, its operands can also be refined. See {@link

 * #propagateToSubtractionOperands(LessThanLengthOf, NumericalSubtractionNode, TransferInput,
 * CFStore)}, and {@link #propagateToMultiplicationOperand(LessThanLengthOf, Node, Node,
 * TransferInput, CFStore)} for details.
