I might be willing to take a stab at using `llvm/Support/thread.h`, but it should be in a separate patch, because I think this should one not be any functional change.  Using `llvm/Support/thread.h` would potentially allow us to get rid of some of the ugly preprocessor defines in `Parallel.h` though, so I think we should do it.

Using `ThreadPool.h` seems a little more risky.  It's almost certain there are subtle differences in the semantics between the two things being used, so it would need to be done much more carefully.
