[DAG] visitShiftByConstant - replace constant detection with FoldConstantArithmetic

Instead of checking that an operand is constant/opaque before calling getNode() and then checking that the result is a constant, just use FoldConstantArithmetic which will just early-out if the operands are not constant foldable.
