It is also possible that we can fix this as a more general problem in DAGCombine (similar to what I said in the previous comment), but instead of having a extract-element-centric solution, we have some other kind of solution. For example something that looks at all converts in the DAG and removes unnecessary ones. So again, consider my previous comment as an example of a more general solution which might be practical. There might be better alternatives.
