#1791 Added hash function for value class. It uses the Visit function and has specialization for the bool_type and <vector> type but was missing specialization for the nullptr. Nullptr caused compilation issues for RHEL, SLES and CentOS.

Enable with MIGRAPHX_ENABLE_CK=1 and --exhaustive-tune tune flag
