PS17, Line 48: public class ExtractLiteralAgg extends RelOptRule {

So the current plan is to get as many queries running as possible.   This 
specific commit ensures that tpcds and tpch will work which gives us some 
confidence that a lot of general queries will work.

I currently have some patches locally that address performance (though there is 
still work to be done, even on top of that).  Some of the current things under 
development are handling partition pruning, adding lots more rules, and dealing 
with stats and keys that determine join ordering.

If you can do me a favor:  Please file a Jira for this as a potential 
optimization.  There is an umbrella Jira, IMPALA-12871, being used for this, so 
if you can create a sub-task here, that would be great, thanks!
