SPARK-4814 [CORE] Enable assertions in SBT, Maven tests / AssertionError from Hive's LazyBinaryInteger

This enables assertions for the Maven and SBT build, but overrides the Hive module to not enable assertions.

Author: Sean Owen <[email protected]>

Closes apache#3692 from srowen/SPARK-4814 and squashes the following commits:

caca704 [Sean Owen] Disable assertions just for Hive
f71e783 [Sean Owen] Enable assertions for SBT and Maven build
