Turned out to be a 2-line fix, but the compiler fallout was huge.

Turns out the pass in resolve was a little too eager to travel back up the
hierarchy chain when looking for trait candidates.

pcwalton says this is right, and it looks right to me too.

I'm not sure if this was even intentional at this point.

r? @nikomatsakis
for the borrow checker changes. Write guards are now eliminated.

This ensures that the `crate_type` attribute always contains a value,
and does not contain an invalid value.
Fixes #11256.

Had to change some stuff in typeck to bootstrap (getting methods in fmt off of Either), but other than that not so painful.

The resulting symbol names aren't very pretty at all:
trait Trait { fn method(&self); }
impl<'a> Trait for ~[(&'a int, fn())] { fn method(&self) {} }
gives
Trait$$UP$$VEC$$TUP_2$$BP$int$$FN$$::method::...hash...::v0.0
However, at least it contain some reference to the Self type, unlike
`Trait$__extensions__::method:...`, which is what the symbol name used
to be for anything other than `impl Trait for foo::bar::Baz` (which
became, and still becomes, `Trait$Baz::method`).

None of these primitives should be Freeze because sharing them in an Arc is a
very bad idea.

cadencemarseille/rust/issue-10755-ICE-for-missing-linker, r=alexcrichton
Trap the io_error condition so that a more informative error message is
displayed when the linker program cannot be started, such as when the
name of the linker binary is accidentally mistyped.

We decided in the 12/10/13 weekly meeting that trailing commas should be
accepted pretty much anywhere. They are currently not allowed in struct
patterns, and this commit adds support for that.

With the old `for` gone, this behaviour is no longer conflicting with
that use of `return` in closures, and this allows shortcircuiting in a
closure.

This code in resolve accidentally forced all types with an impl to become
public. This fixes it by default inheriting the privacy of what was previously
there and then becoming `true` if nothing else exits.

If it's a trait method, this checks the stability attribute of the
method inside the trait definition. Otherwise, it checks the method
implementation itself.

This pull request completely rewrites std::comm and all associated users. Some major bullet points
* Everything now works natively
* oneshots have been removed
* shared ports have been removed
* try_recv no longer blocks (recv_opt blocks)
* constructors are now Chan::new and SharedChan::new
* failure is propagated on send
* stream channels are 3x faster
I have acquired the following measurements on this patch. I compared against Go, but remember that Go's channels are fundamentally different than ours in that sends are by-default blocking. This means that it's not really a totally fair comparison, but it's good to see ballpark numbers for anyway
```
oneshot stream shared1
std 2.111 3.073 1.730
my 6.639 1.037 1.238
native 5.748 1.017 1.250
go8 1.774 3.575 2.948
go8-inf slow 0.837 1.376
go8-128 4.832 1.430 1.504
go1 1.528 1.439 1.251
go2 1.753 3.845 3.166
```
I had three benchmarks:
* oneshot - N times, create a "oneshot channel", send on it, then receive on it (no task spawning)
* stream - N times, send from one task to another task, wait for both to complete
* shared1 - create N threads, each of which sends M times, and a port receives N*M times.
The rows are as follows:
* `std` - the current libstd implementation (before this pull request)
* `my` - this pull request's implementation (in M:N mode)
* `native` - this pull request's implementation (in 1:1 mode)
* `goN` - go's implementation with GOMAXPROCS=N. The only relevant value is 8 (I had 8 cores on this machine)
* `goN-X` - go's implementation where the channels in question were created with buffers of size `X` to behave more similarly to rust's channels.

This will be used for the new `Cell`.
