4519f54857 Warn for unused variables 
Modify typestate to check for unused variables and emit warnings
where relevant. This exposed a (previously harmless) bug in
collect_locals where outer functions had bit-vector entries
for init constraints for variables declared in their inner
nested functions. Fixing that required changing collect_locals to
use visit instead of walk -- probably a good thing anyway.

4165d3640a Add a pass to fold out items that do not belong in the current configuration 
The parser needs to parse unconfigured items into the AST so that they can
make the round trip back through the pretty printer, but subsequent passes
shouldn't care about items not being translated. Running a fold pass after
parsing is the lowest-impact way to make this work. The performance seems
fine.

afc8a5c031 Convert the eval::env to an ast::crate_cfg 
crate_cfg will replace eval::env as the mechanism for conditional compilation.

d53bfad8e7 Introduce a config property to the crate AST node 
This represents the compilation environment, defined as AST meta_items, Used
for driving conditional compilation and will eventually replace the
environment used by the parser for the current conditional compilation scheme.

31ec26d46a Make calling resource destructors work cross-crate 
Tydescs are currently re-created for each compilation unit (and I
guess for structural types, they have to be, though the duplication
still bothers me). This means a destructor can not be inlined in the
drop glue for a resource type, since other crates don't have access to
the destructor body.

Destructors are now compiled as separate functions with an external
symbol that can be looked up in the crate (under the resource type's
def_id), and called from the drop glue.

190644063e Be more strategic about linking to rust crates 
Instead of linking directly to the rust crate, try to figure out the location
and name of the library from the file name, then call gcc with appropriate -L,
-l flags. This will allow dynamic linking to be more forgiving about where it
loads the library from at runtime - currently a stage3 compiler can't run
correctly from the stage0 directory. Only tested on Linux. Fingers crossed.

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.

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.

1a6d029b07 Emit a better error message for unbound type parameters in nested functions 
This code was causing a bounds check failure:

fn hd[U](&vec[U] v) -> U {
  fn hd1(&vec[U] w) -> U {
    ret w.(0);
  }
  ret hd1(v);
}

because in hd1, U was being treated as if it referred to a type
parameter of hd1, rather than referring to the lexically enclosing binding
for U that's part of hd.

I'm actually not sure whether this is a legit program or not. But I wanted
to get rid of the bounds check error, so I assumed that program shouldn't
compile and made it a proper error message.

7fb35ecf84 Serialize constraints in types (literal arguments still not supported) 
This involved, in part, changing the ast::def type so that a def_fn
has a "purity" field. This lets the typechecker determine whether
functions defined in other crates are pure.

It also required updating some error messages in tests. As a test
for cross-crate constrained functions, I added a safe_slice function
to std::str (slice(), with one of the asserts replaced with a
function precondition) and some test cases (various versions of
fn-constraint.rs) that call it. Also, I changed "fn" to "pred" for
some of the boolean functions in std::uint.

Right now rustc hardcodes -lrustllvm. The idea is to instead remember all the native

library that is installed in an unusual location, Graydon suggested using metadata:

native module foo = "bar" {

This reduces some redundancy in the AST data structures and cruft in

ast::local_def, which adds the local crate_num to the given node_id.
Most code only deals with crate-local node_ids, and won't have to
create def_ids at all.

514813148b rustc: Store the lhs and rhs of receive exprs in left to right order 
With the changing of receive semantics the parser has been putting the rhs
expression in the first argument of expr_recv and the lhs in the second, and
all subsequent passes have been referring to them backwords (but still doing
the right thing because they were assuming that lhs was the port and rhs was
the receiver).

This makes all code agree on what lhs and rhs mean for receive expressions.

7fc89f573d Restructure the "checking" pass in typestate 
I noticed that typestate was being lazier than it should be,
because it was only checking typestate for statements and
top-level expression (that is, the expression in a stmt_expr, but
not any subexpressions). So I rewrote the checks in tstate/ck.rs
to use walk, which exposed a few bugs in typestate that I fixed.

Also added some more test cases for if-check.

219924e669 Bring back if-check 
Add "if check" (expr_if_check), a variation on check that executes
an "else" clause rather than failing if the check doesn't hold.

15f71b3600 Refactor ast::item representation 
Most of the fields in an AST item were present in all variants. Things
could be simplified considerably by putting them in the rec rather
than in the variant tags.

a5bca7df88 Refactor data structures representing constraints (again...) 
I added a "resolved" version of the ast::constr type -- ty::constr_def
-- that has a def_id field instead of an ann_field. This is more
consistent with other types and eliminates some checking.

Incidentally, I removed the def_map argument to the top-level function
in middle::alias, since the ty::ctxt already has a def_map field.
