73e6a4f9e5 Elide existing main function when building a test runner. Issue #428 
This prevents any defined main function from colliding with the one
synthesized for the test runner. This is not the best solution since it
doesn't compile a function the user defined, but I don't think it's likely to
be a problem in the near term.

f7a1006a07 Make resolve check for type-variable name-shadowing

this commit implements that check in resolve, avoiding a potential
assertion failure in trans.

21b94d57d5 Change typestate to use visit instead of walk 
Typestate was failing to check some code because if it saw an item,
it would quit immediately. This was to avoid checking nested items
in the same context as the lexically enclosing item, but it was
having the wrong effect: not checking the code after the item at all.

Fixed by switching to visit and skipping over items in a proper
nested fashion. Closes #668.

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.

Closes #665.

a84310aa48 Started working on MapReduce. 
Currently it's only sequential, but it can do word frequency
counting. In an ideal world it would all be polymorphic, but that
pushes the limits of our type system right now. We can generalize it
later.

4739953b84 Fixed two races. 
The first is that the memory_region destructor would complain there is
still an outstanding allocation. This is because circular_buffer from
rust_chan wasn't refing its task, so the task was being destructed too
soon.

The second was where the program could deadlock while joining a
task. The target task would die in the time between checking whether
the task should block and then actually blocking. The fix is to use
the target task's lock.

8acadb17c2 Work on debugging race conditions. 
Ports and channels have been moved to the kernel pool, since they've
been known to outlive their associated task. This probably isn't the
right thing to do, the life cycle needs fixed instead.

Some refactorying in memory_region.cpp. Added a helper function to
increment and decrement the allocation counter. This makes it easier
to switch between atomic and non-atomic increments. Using atomic
increments for now, although this still does not fix the problem.

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.

(The old syntax is still supported as well, for now.)

It is now possible to leave out the parens around if, while, and
do/while conditions, and around alt expressions. Cases in an alt block
can now leave off the case keyword and parens around the pattern.

After the next snapshot, we can start migrating our code to use the
new alt syntax, probably with a pretty-printer pass. The paren-free
syntax will remain optional (you may always parenthesize expressions),
but the old case syntax will no longer be supported in the future.

f279e0d76e Handle pattern-bound upvars 
If a closure inside a case alternative (for example, a for each loop)
referenced a pattern-bound variable, this would cause an assertion
failure in trans. Changed trans::collect_upvars to handle pattern-bound
vars correctly.

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

6fd6fdea93 Move everything syntax-related to syntax/, break deps on rest of compiler 
src/comp/syntax is currently just a sub-module of rustc, but it will,
in the near future, be its own crate. This includes:

 - The AST data structure
 - The parser
 - The pretty-printer
 - Visit, walk, and fold
 - The syntax extension system
 - Some utility stuff that should be in the stdlib*

*) Stdlib extensions currently require a snapshot before they can be
   used, and the win build is very broken right now. This is temporary
   and will be cleaned up when one of those problems goes away.

A lot of code was moved by this patch, mostly towards a more organized
layout. Some package paths did get longer, and I guess the new layout
will take some getting used to. Sorry about that!

Please try not to re-introduce any dependencies in syntax/ on any of
the other src/comp/ subdirs.

046c25dbc0 Handle fail as an argument; parse fail expressions unambiguously 
An expression like:

foo(1, fail, 2)

was failing to parse, because the parser was interpreting the comma
as the start of an expression that was an argument to fail, rather
than recognizing that the fail here has no arguments

Fixed this by using can_begin_expr to determine whether the next
token after a fail token suggests that this is a nullary fail or a
unary fail.

In addition, when translating calls, check before translating each
argument that the block still isn't terminated. This has the effect
that if an argument list includes fail, the back-end won't keep trying
to generate code for successive arguments and trip the !*terminated
assertion.

432e5e9f7f Allow dereferencing of single-variant, single-argument tag values 
(Using the * operator.)

This makes tags more useful as nominal 'newtype' types, since you no
longer have to copy out their contents (or construct a cumbersome
boilerplate alt) to access them.

I could have gone with a scheme where you could dereference individual
arguments of an n-ary variant with ._0, ._1, etc, but opted not to,
since we plan to move to a system where all variants are unary (or, I
guess, nullary).

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.

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.
