RFR 8014076: Arrays parallel and serial sorting improvements

[Chris Hegarty]

Doug,

David raises a good question here. Is this implementation detail still 
correct:
   "The algorithm requires a working space equal to the size of the
original array."

I did get clarifications on a number of the minor spec/implementation 
details, but I don't think we discuss this one.

  (I believe lambda's version of Arrays was not sync'ed with TL after 
integration of parallelSort, and before Doug did his work. Or at least 
there was some confusion about the latest version of this file).

-Chris.
