[TRAFODION-2983] Be careful to preserve inputs needed for output computation
This fix changes GroupByAgg::tryToPullUpPredicatesInPreCodeGen
(optimizer/RelExpr.cpp) to make sure that characteristic inputs needed to
calculate characteristic output expressions are not removed.
It also makes a small improvement to some ValueId Equivalence Group (VEG)
debugging code.
