Refactoring and reorganisation of the scheduler

Change the way we look for work in the scheduler.  Previously,
checking to see whether there was anything to do was a
non-side-effecting operation, but this has changed now that we do
work-stealing.  This lead to a refactoring of the inner loop of the
scheduler.

Also, lots of cleanup in the new work-stealing code, but no functional
changes.

One new statistic is added to the +RTS -s output:

  SPARKS: 1430 (2 converted, 1427 pruned)

lets you know something about the use of `par` in the program.
