Commit 3e1e7da229913ac1651ea908e8817d6e41adf8b0 in impala's branch
refs/heads/master from Tim Armstrong

IMPALA-9898: generate grouping set plans
Integrates the parsing and analysis with plan generation.
Testing:
* Add analysis test to make sure we reject unsupported queries.
* Added targeted planner tests to ensure we generate the correct
aggregation classes for a variety of cases.
* Add targeted end-to-end functional tests.
Added five TPC-DS queries that use ROLLUP, building on some work done
by Fang-Yu Rao. Some tweaks were required for these tests.
* Add an extra ORDER BY clause to q77 to make fully deterministic.
* Add backticks around `returns` to avoid reserved word.
* Add INTERVAL keyword to date/timestamp arithmetic.
We can run q80, too, but I haven't added or verified results yet -
that can be done in a follow-up.
