exponential complexity in ORC predicate conversion

   @IvanVergiliev I agree we should automate running these micro benchmark 
tests to ensure we do not have the regressions. However, Apache Spark does not 
do it now. In my company, we have a different framework that run the 
microbenchmark suites for Spark to ensure we do not have perf regressions. For 
more details, you can see the talk:

   The micro benchmark suites this PR changed are used to compare the perf 
difference among the similar but related cases. For example, turning on/off a 
specific conf. You can create a new perf suite for showing the cost per filter 
and put them in a single test case? We can check `Relative` to know whether it 
has a regression?
