GEODE-2587: Refactored the OrderByComparator's compare method

	* This prevents creation of extra data structures like arrays of arrays
	* Hence let number of GC, faster execution of queries with ORDER BY

	This closes #517

> OrderByComparator's compare method creates a lot of objects / arrays with the intention
of comparing two objects.
> But allocation of memory for these objects results in GC to kick in.
> The additional time consumed in GC results in increased execution time for queries with
ORDER BY clause.
> This method must be refactored to require less memory allocations in order to compare
and thus speed up ORDER BY clause.
