Review Comment:
   @HyukjinKwon any chance we could modify this change to make it acceptable or 
should it just be abandoned?
   
   I also notice that we will attempt to execute expressions and therefore UDFs 
as part of `EliminateOuterJoins`. There errors are ignored. We could extend the 
`ConstantFolding` rule to the same, ignore errors from expressions containing 
UDFs?
