Review comment:
       Only RexCall has getOperands. I was under the impression that these 
operands are garenteed to be prior entries returned in ExprList. It will be a 
little while before I have time to verify. If that is not the case, it is easy 
to transform the ExprList into that form. That will need to be true for this to 
be correct and for calc splitting to be easy.
