IMPALA-10843: fix NullPointerException when print the low and high value of the
column on which the filter is applied
We should check whether the low and high value of the column on which
the filter is applied is null when printing in TRACE log level.
Testing:
Start impala in TRACE log level and manually test the following
queries:
1. compute stats functional_parquet.testtbl
2. select id from testtbl t1 join jointbl t2 on t1.id=t2.test_id
