    Implement the parallel upsweep (#910)
    
    The parallel upsweep is the parallel counterpart to the default
    sequential upsweep. It attempts to compile modules in parallel by
    subdividing the work of the upsweep into parts that can be executed
    concurrently by multiple Haskell threads.
    
    In order to enable the parallel upsweep, the user has to pass the -jN
    flag to GHC, where N is an optional number denoting the number of jobs,
    or modules, to compile in parallel, like with GNU make. In GHC this just
    sets the number of capabilities to N.
