9f61e542b4 Move rm -rf to the beginning of the test
While the discussion about how to refactor test framework is not
finished (#1654), make this change: move `rm -rf build` in the
beginning of the test. For these reasons:

* it is useful to inspect the contents of the `build` directory
  especially after the test failure
* if build crashes mid-test (e.g. process killed), next run should
  not be affected by the `build` directory from the previous run

ad632d825d Remove linearity subtyping
It's disappointing to have to do this, but I think necessary because
various issue reports have shown it to be unsound (at least as far as
inference goes) and, at the very least, confusing. This patch brings us
back to the basic rules of QTT.

On the one hand, this makes the 1 multiplicity less useful, because it
means we can't flag arguments as being used exactly once which would be
useful for optimisation purposes as well as precision in the type. On
the other hand, it removes some complexity (and a hack) from
unification, and has the advantage of being correct! Also, I still
consider the 1 multiplicity an experiment.

We can still do interesting things like protocol state tracking, which
is my primary motivation at least.

Ideally, if the 1 multiplicity is going to be more generall useful,
we'll need some kind of way of doing multiplicity polymorphism in the
future. I don't think subtyping is the way (I've pretty much always come
to regret adding some form of subtyping).

Fixes #73 (and maybe some others).

c9b20911e1 Add linear pair/dependent pair to the prelude
I'm playing with some linear structures and finding these useful a lot,
so good to have a consistent syntax for it. '#' is chosen because it's
short, looks a bit like a cross if you look at it from the right angle
(!) and so as not to clash with '@@' in preorder reasoning syntax.

a972778eab Add test script
They don't all pass yet, for minor reasons. Coming shortly...
Unfortunately the startup overhead for chez is really noticeable here!
