9561def209 Use 'resource' rather than 'res' as a keyword
Resources are now defined like...

    resource fd(int n) { close(n); }

Calling fd with an int will then produce a non-copyable value
that, when dropped, will call close on the given int.

be748fc215 Properly guard resource values against double-drop
Ths involved adding an extra field to their representation, so that there is
something to check for zero.

ecc080ed0b Use "" in the native_name as an indication that no extra options have to
be passed to the "linker". Use that for libc.

85b5b2a8e4 Tests for while loops that may invalidate constraints
Wrote some small test cases that use while loops and moves, to
make sure the poststate for the loop body gets propagated into the
new prestate and deinitialization gets reflected.

Along with that, rewrite the code for intersecting states. I still
find it dodgy, but I guess I'll continue trying to add more tests.
Also, I'll probably feel better about it once I start formalizing
the algorithm.

6d1050b1c7 pure_exp should set the state, not extend it
This fixes a bug where de-initializations were getting masked
(and programs that used a variable that had been de-initialized
snuck through).

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,

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.
