a9a1392b2c Instantiate function preconditions inside the function body 
so that if we have a function like:
f(...) : p(x) {
  ...
}

p(x) is true inside the body of f.

Closes #694.

3ae4dcd41e Lots of work on memory tracking and channels. 
We're trying to get closer to doing correct move semantics for channel
operations. This involves a lot of cleanup (such as removing the
unused sched parameter from rust_vec constructor) and making
circular_buffer kernel_owned.

Added tagging for memory allocations. This means we give a string tag
to everything we allocate. If we leak something and TRACK_ALLOCATIONS
is enabled, then it's much easier now to tell exactly what is leaking.

bd4aeef78b Beginnings of support for constrained types 
Programs with constrained types now parse and typecheck, but
typestate doesn't check them specially, so the one relevant test
case so far is XFAILed.

Also rewrote all of the constraint-related data structures in the
process (again), for some reason. I got rid of a superfluous
data structure in the context that was mapping front-end constraints
to resolved constraints, instead handling constraints in the same
way in which everything else gets resolved.

f4beac4a43 Revert "Allow main to return int" 
This reverts commit 8c94d8fd54.

There's no mechanism to actually return the value from main, so all this does
is allow main -> int to compile. Per #688, the program returns non-zero on
failure, so it's not obvious that this change is appropriate at this time.

e1620def9f In typeck, check for dynamically sized by-value arguments to thunks 
A check in trans didn't have a corresponding check in typeck, causing
some programs (to wit, compile-fail/chan-parameterized-args.rs - part of this
commit) to fail with an assertion failure in trans instead of a type error.
Fixed it. In short, arguments that are future thunk arguments (any spawn
arguments, and _ arguments in bind) need to either not contain type params
or type vars, or be by-reference.

c7bfef43c8 Ignore current scope when resolving self-shadowing imports 
That is, for example, import x::y::x, which defines a local x,
and thus wouldn't be able to find x::y anymore.

Removes ty::strip_boxes entirely, since unboxing is now more complicated
anyway.

3243144046 Fix a bug that was interfering with method overriding. Issue #543. 
Previously, we were creating both a normal vtable entry and a
forwarding function for overriding methods, when they should have just
gotten a vtable entry.  This patch fixes that.

16f82dce1c Clean up trans_arg_expr 
As a preparation for implementing the temporary-move optimization for
argument passing. The optimization itself isn't in yet, since it
mysteriously corrupts memory.

3bdbf74d47 Make moving of temporaries do the right thing, use it to optimize 
This adds support for dropping cleanups for temporary values when they
are moved somewhere else. It then adds wraps most copy operations
(return, put in data structure, box, etc) in a way that will fall back
to a move when it is safe.

This saves a lot of taking/dropping, shaving over a megabyte off the
stage2/rustc binary size.

In some cases, most notably function returns, we could detect that the
returned value is a local variable, and can thus be safely moved even
though it is not a temporary. This will require putting some more
information in lvals.

I did not yet handle function arguments, since the logic for passing
them looked too convoluted to touch. I'll probably try that in the
near future, since it's bound to be a big win.

failure in trans. Changed trans::collect_upvars to handle pattern-bound

Incidentally, eliminated all direct uses of option::get in trans.
