Dimitris Tsirogiannis d04f190973 IMPALA-1802: Impala produces incorrect count(distinct) result with limit

clause

This commit fixes the issue where if a query contains a count(distinct)
expression in conjunction with a limit, the limit is incorrectly applied
to the wrong place in the generated plan, thereby producing incorrect
results.

This directory contains Impala test workloads. The directory layout for the workloads should follow:

workloads/
   <data set name>/<data set name>_dimensions.csv  <- The test dimension file
   <data set name>/<data set name>_core.csv  <- A test vector file
   <data set name>/<data set name>_pairwise.csv
   <data set name>/<data set name>_exhaustive.csv
   <data set name>/queries/<query test>.test <- The queries for this workload
