URL: https://github.com/apache/orc/pull/1082

   ### What changes were proposed in this pull request?
   
   This pr is aimed at using `isNaN` instead of `isFinite` to determine the 
contain NaN values.
   I want to exclude Double.POSITIVE_INFINITY / Double.NEGATIVE_INFINITY both 
cases, and only match NaN.
   
   ### Why are the changes needed?
   
   In the case of a sum overflow we can also predicate down to skip the 
corresponding strip.
   
   ### How was this patch tested?
   
   Added unit test.
