> Grouping sets is broken for >32 columns because of usage of Int for bitmap 
> (also GROUPING__ID virtual column). This assumption breaks grouping 
> sets/rollups/cube when number of participating aggregation columns is >32. 
> The easier fix would be extend it to Long for now. The correct fix would be 
> to use BitSets everywhere but that would require GROUPING__ID column type to 
> binary which will make predicates on GROUPING__ID difficult to deal with.
