Title:  DB2 HQL insert statement (https://hibernate.onjira.com/browse/HHH-7558)

the problem here is that during the Session Factory initialization
the sqlFunctions register Long data type as (big_integer ),while
DB2Dialect class register it as
(bigint) so when hibernate trying to find the data type of
(bigint) in SqlFunctions (big_integer) hibernate throw null Pinter
Exception ,
I change bigint to big_integer in DB2Dialect class and it works now
