casey 516d7483dd IMPALA-1300: Allow subqueries in UNION operands

This enables the existing subquery rewrite rules to rewrite UNION
statements. UNION rewriting is easily done by simply calling the
rewriter for each operand in the UNION. At least one TPC-DS query
requires this functionality (IMPALA-1365).

The more difficult case of a UNION within a subquery is still not
supported.

README

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
