Latest patch should fix the order by desc issue.  Also, a new desc test case 
has been added for the 3 functions.

The ntile and percent_rank did not need to be changed because the order by 
clause is not reversed in that case as specified in AnalyticExpr.java.


The Impala code has some more order by situations that are handled but are not 
in the test framework.  These include when the order by column has multiple 
columns and if the null direction is changed.  I filed issue IMPALA-13562 for 
this.
