This is necessary to pass the lit test suite at llvm/utils/lit/tests.
There are some pre-existing failures here, but now switching to pools
doesn't regress any tests.
I had to change test-data/lit.cfg to import DummyConfig from a module to
fix pickling problems, but I think it'll be OK if we require test
formats to be written in real .py modules outside lit.cfg files.
I also discovered that in some circumstances AsyncResult.wait() will not
raise KeyboardInterrupt in a timely manner, but you can pass a non-zero
timeout to work around this. This makes threading.Condition.wait use a
polling loop that runs through the interpreter, so it's capable of
asynchronously raising KeyboardInterrupt.

- This is a work-in-progress and all details are subject to change, but I am
trying to build up support for allowing lit to be used as a driver for
performance tests (or other tests which might want to record information
beyond simple PASS/FAIL).
