Skip unnecessary get all partition operations when where condition with 1=0 in CBO.

In some cases, queries may get executed with where condition mentioning to "1=0" to get schema. E.g

SELECT
  *
FROM
  table_with_millions_of_partitions
WHERE
  1=0

In actual production, it likes:

SELECT
  *
FROM
  table_with_millions_of_partitions
WHERE
  partition_col1 = value1
  and partition_col2 = value2
  and if(some conditions, true, false)

When the cbo optimizer optimizes the execution plan of this query, the cbo optimizer will get all the partitions of table_with_millions_of_partitions. This seems useless and causes hiveserver to fail when the number of partitions is very high.

Use this patch to skip unnecessary get all partition operation when pruneNode is always false.
