SQL functions with constant values

   @lushuifeng, thanks for the contribution!
   
   Could you please provide the time of execution of the query with and without 
your change?
   
   Please note, that Drill has its own framework for scalar replacement and 
passing value holders to the methods as arguments may break a scalar 
replacement for those holders.
   
   Also, Drill can generate too large classes. To avoid problems with the class 
constant pool overflow was implemented splitting the classes into the smaller 
ones. Is this change incorporates or at least does not break it?
