> HIVE-10238 showed that ?: operator can be optimized with bitwise operators when it only
handles LongColumnVectors. There are more similar cases as following.
> IfExprLongColumnLongScalar: {code}outputVector[i] = (vector1[i] == 1 ? vector2[i] : arg3Scalar);{code}
> IfExprLongScalarLongColumn: {code}outputVector[i] = (vector1[i] == 1 ? arg2Scalar : vector3[i]);{code}
> IfExprLongScalarLongScalar: {code}outputVector[i] = (vector1[i] == 1 ? arg2Scalar : arg3Scalar);{code}
