performance improvement in POUserFunc
-------------------------------------

Key: PIG-358
URL: https://issues.apache.org/jira/browse/PIG-358
Project: Pig
Issue Type: Improvement
Reporter: Olga Natkovich


Currently, it has the following code in processInput:

if(rslt.size()==1 && rslt.get(0) instanceof Tuple){
res.result = rslt.get(0);
}

Note it does getInstance on every Tuple it process even though it should already know from the return type.
