This pr add pull up literal when infer predicates, we can infer
tmp.col1='abc' and tmp.col2 = 'def' from subquery tmp, pull up to inner
join, and combined with join on condition, we can infer ds.col1='abc'
and ds.col2='def'
select
*
from
(
select
tmp.col1,
tmp.col2
from
(
select
'abc' as col1,
'def' as col2
from
