020e3967f7 Change order of arguments to test functions 
1. Discard function (if present)
2. Way              (if present)
3. Memory type      (if present)
4. Name of test
5. Predicate
6. Action

For multi-predicate functions, 4 and 5 are replaced with a list.

6eaae0a589 Wrap predicate functions in a newtype & separate ty params 
Also adds a Functor and Profunctor instance for predicates.  The old
predicate type is kept as an alias for the (common) case where both
tyvars are the same.

45256193c0 Implement bound threads 
This also adds forkOS(N) and isCurrentThreadBound to MonadConc, a
breaking change.

Note: forkOSWithUnmask(N) is NOT added to MonadConc, as it isn't
supported in base-4.8 (GHC 7.10).  See #132 for the action on this.

A bound thread under test gets a dedicated worker thread, which is
forked bound using the underlying MonadConc.  This worker is used for
all lifted actions, with execution as normal otherwise.

31d29c11ea Require a 'MonadConc n' instance to run 'ConcT r n' expressions 
This is preparation for adding bound threads.  The instance isn't used
in this commit, but the diff is large enough that I feel this should
be a separate commit for ease of review.

Fallout:

- The MonadBaseControl IO instance is gone, as I'm not sure how to do
  it generally.
- The pure/IO split is gone, everything is now monadic.
- The execution, SCT, and dejafu functions are of the form (MonadConc
  n, MonadRef r n) => ...

7d5df170e7 Do not pass memory model to dependency functions 
This is sane because buffered writes can only happen if the MemType
isn't sequential consistency anyway.
