JIRA TRAFODION-2099 Add support for boolean datatype
-- boolean datatype support in create, cast and params
Ex:
create table t (a boolean);
insert into t values (true), (false);
select * from t where a = true;
-- boolean datatype support for hive columns
-- unarith op support. Currently used for '!' operator that
negates a boolean value.
Ex: select * from t where !a = false;
-- support for more tinyint and largeint unsigned conversion/comparison
operations in expressions and pcode
-- some code cleanup: removed reference to downrev compiler code genration
-- create table if not exists as select... syntax support
-- regress/seabase/TEST003 updated with additional tests
