* 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.
