Summary: is not null syntax error

Initial Comment:
The following sql statements gave an expected syntax error:

create function f1()
RETURNS int
BEGIN
        return 0;
END;

create table t1 (id int);
select id from t1 where f1() IS NOT NULL;

drop function f1;
drop table t1;



MAPI  = [EMAIL PROTECTED]:50000
QUERY = select id from t1 where f1() IS NOT NULL;
ERROR = !syntax error, unexpected IS, expecting SCOLON in: "select id from t1 
where f1() is"

there where 2 bugs. 1) we didn't handle arbitrary expressions before the
IS NOT NULL and this a special case predicate (return all or nothing).
Both problems are fixed.
