7c500fc0a0 Replace common::new_seq_hash with an adapter around std::smallintmap
It would be better to either convert ast_map to use smallintmap or make
smallintmap and hashmap follow the same interface, but I don't feel up to
it just now. Closes #585.

9f1444c701 Implement "claim"
Implement "claim" (issue #14), which is a version of "check" that
doesn't really do the check at runtime. It's an unsafe feature.

The new flag --check-claims turns claims into checks automatically --
but it's off by default, so by default, the assertion in a claim
doesn't execute at runtime.

a83b64d15d Rework how linkage attributes are determined
The meta items within a crate's link attribute are used in linkage:

 #[link(name = "std",
        vers = "1.0",
        custom = "whatever")];

Name and vers are treated specially, and everything else is hashed together
into the crate meta hash.

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).

36fb754476 Index obj and res ctor metadata by ctor id, not item id

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.

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.
