f79f7fd245 Add a MonadSTM 
- Each MonadConc has an associated MonadSTM, transactions of which
   it can run atomically.
 - The MonadSTM for IO is STM.
 - Conc and ConcIO do not yet have a MonadSTM.

7aceb6a6f9 Implement an atomic-for-testing-purposes function. 
This adds a new `MonadConc` primitive, `_concNoTest`, which is (for
all non-test implementations) the identity function. For test
implementations, it is understood as "this action is completely safe
under all schedules, so just execute it all at once and don't consider
any internal interleavings." It is not required to be deterministic,
merely to never fail.

Actions annotated with `_concNoTest` will show up as one step in the
trace, and new `Failure` and `ThreadAction` values have been added.
