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.
