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.
