[WIP][SPARK-4937][SQL] Adding optimization to simplify the  And, Or condition in spark sql

Adding optimization to simplify the filter condition(https://issues.apache.org/jira/browse/SPARK-4938)
1 condition that can eliminated by boolean result such as:
a < 3 && a > 5 ---- False
a < 1 || a > 0 ---- True

2 Simplify And, Or condition, such as the sql (one of hive-testbench):
```
select
sum(l_extendedprice* (1 - l_discount)) as revenue
from
lineitem,
part
where
(
p_partkey = l_partkey
and p_brand = 'Brand#32'
and p_container in ('SM CASE', 'SM BOX', 'SM PACK', 'SM PKG')
and l_quantity >= 7 and l_quantity <= 7 + 10
and p_size between 1 and 5
and l_shipmode in ('AIR', 'AIR REG')
and l_shipinstruct = 'DELIVER IN PERSON'
)
or
(
p_partkey = l_partkey
and p_brand = 'Brand#35'
and p_container in ('MED BAG', 'MED BOX', 'MED PKG', 'MED PACK')
and l_quantity >= 15 and l_quantity <= 15 + 10
and p_size between 1 and 10
and l_shipmode in ('AIR', 'AIR REG')
and l_shipinstruct = 'DELIVER IN PERSON'
)
or
(
p_partkey = l_partkey
and p_brand = 'Brand#24'
and p_container in ('LG CASE', 'LG BOX', 'LG PACK', 'LG PKG')
and l_quantity >= 26 and l_quantity <= 26 + 10
and p_size between 1 and 15
and l_shipmode in ('AIR', 'AIR REG')
and l_shipinstruct = 'DELIVER IN PERSON'
)
```
It has a repeated expression in Or, so we can optimize it by ``` a && (b || c) = (a && b) || (a && c)```
Before optimization, this sql hang in my locally test, and the physical plan is:

After optimization, this sql run successfully in 20+ seconds, and its physical plan is:

The same as `CombinePredicate`, we'd better not combine the existed expression with the `Optimizer`.
