Subject [Impala-CR](cdh5-trunk) IMPALA-2805: Order filters based on selectivity and cost

Change subject: IMPALA-2805: Order filters based on selectivity and cost
......................................................................


Patch Set 4:

I think it's comparing against an Impala 2.5 baseline rather than 2.6 trunk. E.g. the Q1 perf
change was from an earlier patch. You can manually generate a benchmark report if you grab
benchmark_results.json from the workload runs with your branch and compare with a benchmark_results.json
from a recent nightly run. The script is ./tests/benchmark/report_benchmark_results.py
