36fb754476 Index obj and res ctor metadata by ctor id, not item id
Both the type and the ctor were trying to use the same id and this was making
creader unable to find the ctor when running 'rustc --ls'

1656fa19ef Implement move for scalar values
Before, something like:

let int y = 42;
let int x;
x <- y;

would cause an LLVM assertion failure. Fixed it.

cfaa0f4b91 Fail typechecking for bad binop/type combinations
Includes assignment operations. Add regression tests for lots of less useful,
less used or unexpected combinations, as well as a selection of compile-fail
tests. Closes #500 (again!)

Sorry. This is the kind of thing I do when I'm on a plane and too
tired to manage anything that requires thinking.

f6753be655 Allow moving out of temporary values
This will probably need more work, as moving doesn't appear to do
quite the right thing yet in general, and we should also check
somewhere that we're not, for example, moving out the content out of
an immutable field (probably moving out of fields is not okay in
general).

61fc12d0d0 Partial implementation of resources
Non-copyability is not enforced yet, and something is still flaky with
dropping of the internal value, so don't actually use them yet. I'm
merging this in so that I don't have to keep merging against new
patches.

582e1f13f0 Invalidate constraints correctly after an assignment expression
Modified typestate to throw away any constraints mentioning a
variable on the LHS of an assignment, recv, assign_op, or on
either side of a swap.

Some code cleanup as well.

b732ec6f82 Have walk call visit_fn_pre and visit_fn_post on fn expressions.

inside of fn expressions.

2ebd19477b Sanitize use of ids for obj constructors.
Typeck and trans used to, by historical coincidence, use the item_obj
node id, which was used to identify the obj type by the rest of the
system, for the constructor function. This is now identified by the
ctor id stored in the tag throughout.

05c0216654 rustc: Add ternary operator. Closes #565
The implementation is so simple it might be considered cheating: at almost
every step the expr_ternary is just converted to expr_if.

string is enough for rustc right now.

3cf00c1577 Correct error message for argument mode mismatch
If you use a function expecting an alias argument in a context that
expects a function expecting a value argument, or vice versa, the
previous error message complained that the number of arguments was
wrong. Fixed the error message to be accurate.

9a48bd2f21 Compute typestate properly for move
typestate now drops constraints correctly in the post-state of
a move expression or a declaration whose op is a move. It doesn't
yet drop constraints mentioning variables that get updated.

To do this, I had to change typestate to use trit-vectors instead
of bit-vectors, because for every constraint, there are three
possible values: known-to-be-false (e.g. after x <- y, init(y) is
known-to-be-false), known-to-be-true, and unknown. Before, we
conflated known-to-be-false with unknown. But move requires them
to be treated differently. Consider:

(program a)
(a1) x = 1;
(a2) y <- x;
(a3) log x;

(program b)
(b1) x = 1;
(b2) y <- z;
(b3) log x;

With only two values, the postcondition of statement a2 for
constraint init(x) is the same as that of b2: 0. But in (a2)'s
postcondition, init(x) *must* be false, but in (b2)'s condition,
it's just whatever it was in the postcondition of the preceding statement.
