   Thanks for the review @cloud-fan , have addressed all three points:
   - Derive LHS nullability from `valExprs` for `CreateNamedStruct` so nullable 
LHS fields are correctly propagated through generated NOT IN code
   - Split result rows into a TreeSet of fully non-null rows (O(log n) indexed 
lookup) and an array of null-containing rows (linear scan only when needed)
   - Fixed comment to 5+5=10 rows
   - Added nullable-LHS/non-nullable-RHS codegen regression test
   
   Can you PTAL again? Thanks!
