Calculating hashCode of IntRange by pairing function
----
> Calling hashCode on IntRange iterates through all elements in the range.

> {code}
> new IntRange(0, Integer.MAX_VALUE-1).hashCode()
> {code}
> The above code takes a few seconds to complete.
> I believe the hashCode method is not overridden and it defaults to
> AbstractList which iterates through all elements. I don't think this should
> be the default behavior.
