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.

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.

d1857d30fc This is the mega-ucontext commit. It replaces the task switching mechanism with a new one inspired by ucontext. It works under Linux, OS X and Windows, and is Valgrind clean on Linux and OS X (provided the runtime is built with gcc). 
This commit also moves yield and join to the standard library, as requested in #42. Join is currently a no-op though.

e5eacf8ea9 Use RHS type when translating assignments

be copied. Fixed trans to reflect that.

17ff2a0d79 Further support for predicate constraints 
Changed function types to include a list of constraints. Added
code for parsing and pretty-printing constraints. This necessitated
splitting pprust into two files (pprust and ppaux) to break a
circulate dependency, as ty_to_str now needs to print out constraints,
which may include literals, but pprust depended on ty.

537d879dc1 Properly handle lifetime of aliases in nested blocks 
There was a bug that would cause the alias analyser to allow you to
invalidate an alias that was no longer directly referred to, even if
another alias was rooted in it. It now properly tracks dependencies
between live aliases.

Required another case of copying values in map.rs.

beda82ddf1 A revised, improved alias-checker 
The old system tried to ensure that the location an alias pointed at
would retain its type. That turned out to not be strong enough in the
face of aliases to the inside of tags.

The new system instead proves that values pointed to by aliases are
not replaced (or invalidated in some other way) at all. It knows of
two sufficient conditions for this, and tries to prove at least of
them:

A) The alias is 'immutably rooted' in a local, and this local is not
   reassigned for the lifetime of the alias. Immutably rooted means
   the alias refers to the local itself, or to something reachable
   from the local through immutable dereferencing.

B) No value whose type might include the type of the 'inner mutable
   element' of the thing the alias refers to (for example, the box in
   rec(mutable x = @mutable int)) is from the outer scope is accessed
   for the lifetime of the alias. This means for functions, no other
   argument types may include the alias's inner mutable type. For alt,
   for each, and for, it means the body does not refer to any locals
   originating from outside their scope that include this type.

The lifetime of an alias in an alt, for each, or for body is defined
as the range from its definition to its last use, not to the point
where it goes out of scope. This makes working around these
restrictions somewhat less annoying. For example, you can assign to
your alt-ed value you don't refer to any bindings afterwards.

4bd5f834b0 First take on an alias-safety checker 
The alias checker works by ensuring that any value to which an alias
is created is rooted in some way that ensures it outlives the alias.

It is now disallowed to create an alias to the content of a mutable
box, or to a box hanging off a mutable field. There is also machinery
in place to prevent assignment to local variables whenever they are
the root of a live alias.

2b334f061a Change unsafe aliases 
This litters aberrations like 'alt({foo.bar}) { ... }' and f({*baz})
though the code (mostly in trans.rs). These are a way to explicitly
copy the given value so that it can be safely aliased. At some point
we'll probably want a more explicit copy operator.

468786e36d Fix unification bug 
Hello from SFO Terminal 3!

unify_fn_common had the expected and actual types reversed in one
place. This was causing the type of an occurence of a function f
with type fn(int) -> T to be set to fn(_|_) -> T at a call site like
f(fail); I think this was also making some of the type error messages
come out backwards, but I haven't checked.

Also: ty_bot does not contain pointers

7d68cbdff0 Have blocks return their result by writing to a reserved space 
This makes it possible to pass the location of that space through to
nested blocks, resulting in less copying, taking, and dropping.

This makes the compiler slightly faster and 19k smaller.

A FIXME is to use 'move' semantics when returning the values from the
block -- don't bump the refcount and drop it again for the returning
block, but simply assign ownership to the receiver. To do this, we'll
need a way to (safely) scrub things from a block's cleanup list.

accordingly, removed special cases.

essentially a bit of data that says whether or not this function
never returns to the caller (if it never returns, that means it calls
"fail" or another "never-returns" function on every control path).

Also add syntax for annotating functions that never return:

fn foo() -> ! {
   fail;
}

for example. Functions marked with ! implicitly have a result type of
ty_bot, which is a new type that this commit also adds.

8cbdaf4f93 Make trans use span_err for the dreaded "ty_var in trans::type_of" error 
This required quite a bit of tiresome plumbing about of spans.
On the bright side, now other errors can be converted to span_err too.

Includes test cases.

result in a value that requires refcounting then it will need to drop the
refcount in the cleanups of the else block.
