Improve POR for relaxed memory
...
- Refine notion of dependent actions tot ake the memory model into
account.
- Don't consider context switches for commits as viable candidates
for conservative backtracking points.

Parameterise conc runner with memory model to use.
...
Three memory models will eventually be supported:
- SequentialConsistency, which is the current behaviour.
- TotalStoreOrder, where each thread has a write buffer.
- PartialStoreOrder, where each CRef has a write buffer.
The parameter is currently ignored.

Also swap the order of the append in 'prefixes'. For some reason this makes it
work much better in the test cases. No idea why.

Use Set instead of [] where it makes sense.
...
A lot of the places where lists were used, there was an assumed invariant that
there would be no duplicate entries, for some criteria of equality. In some
cases this was enforced by `nub`, in others not. Sets are a much better choice
here, as they actually enforce the invariant, with better complexity for some
operations.
