Lars Volker 749a55c4ad IMPALA-2328: Read support for min/max Parquet statistics

This change adds support for skipping row groups based on Parquet row
group statistics. With this change we only support reading statistics
from Parquet files for numerical types (bool, integer, floating point)
and for simple predicates of the forms <slot> <op> <constant> or
<constant> <op> <slot>, where <op> is LT, LE, GE, GT, and EQ.

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
