Example:
void ({ i64, %tydesc*, i8*, i8*, i8 }*, i64*, %"struct.std::fmt::Formatter[#1]"*)*
Before, we would print 20 levels deep due to recursion in the type
definition.
r? @metajack When I started writing the rustpkg tests, task failure didn't set the
exit code properly. But bblum's work from July fixed that. Hooray! I
just didn't know about it till now.
So, now rustpkg uses exit codes in a more conventional way, and some of
the tests are simpler.
The bigger issue will be to make task failure propagate the error message.
Right now, rustpkg does most of the work in separate tasks, which means if
a task fails, rustpkg can't distinguish between different types of failure
(see #3408)

This patch removes the code responsible for handling older CrateMap versions (as discussed during #9593). Only the new (safer) layout is supported now.
I've left out a way to construct from a `Send` type until #9509 is resolved. I am confident that this interface can remain backwards compatible though, assuming we name the `Pointer` trait method `borrow`.
When there is a way to convert from `Send` (`from_send`), a future RAII-based `Mut` type can be used with this to implemented a mutable reference-counted pointer. For now, I've left around the `RcMut` type but it may drastically change or be removed.
There's currently a fair amount of code which is being ignored on unnamed blocks
(which are the default now), and I opted to leave it commented out for now. I
intend on very soon revisiting on how we perform linking with extern crates in
an effort to support static linking.
I borrow some ideas from clang's ABIInfo.h and TargetInfo.cpp.
LLVMType is replaced with ArgType, which is similar to clang's ABIArgInfo,
and I also merge attrs of FnType into it.
Now ABI implementation doesn't need to insert hidden return pointer
to arg_tys of FnType. Instead it is handled in foreign.rs.
This change also fixes LLVM assertion failure when compiling MIPS target.
r? @pcwalton Sadly, there's a lack of resources for maintaining the `rust` tool,
and we decided in the 2013-10-08 Rust team meeting that it's better
to remove it altogether than to leave it in a broken state.
This deletion is without prejudice. If a person or people appear who
would like to maintain the tool, we will probably be happy to
resurrect it!
Closes#9775

r? @metajack rustpkg now makes source files that it checks out automatically read-only, and stores
them under build/.
Also, refactored the `PkgSrc` type to keep track of separate source and destination
workspaces, as well as to have a `build_workspace` method that returns the workspace
to put temporary files in (usually the source, sometimes the destination -- see
comments for more details).

Some bug fixes to reexported statics in stage0 now, also some macro attribute goodies. Mostly just updating the snapshot to help enable some things that its patches have been blocking.
This fixes a bug in which the visibility rules were approximated by
reachability, but forgot to cover the case where a 'pub use' reexports a private
item. This fixes the commit by instead using the results of the privacy pass of
the compiler to create the initial working set of the reachability pass.
This may have the side effect of increasing the size of metadata, but it's
difficult to avoid for correctness purposes sadly.
Closes#9790
This implements a number of the baby steps needed to start eliminating everything inside of `std::io`. It turns out that there are a *lot* of users of that module, so I'm going to try to tackle them separately instead of bringing down the whole system all at once.
This pull implements a large amount of unimplemented functionality inside of `std::rt::io` including:
* Native file I/O (file descriptors, *FILE)
* Native stdio (through the native file descriptors)
* Native processes (extracted from `std::run`)
I also found that there are a number of users of `std::io` which desire to read an input line-by-line, so I added an implementation of `read_until` and `read_line` to `BufferedReader`.
With all of these changes in place, I started to axe various usages of `std::io`. There's a lot of one-off uses here-and-there, but the major use-case remaining that doesn't have a fantastic solution is `extra::json`. I ran into a few compiler bugs when attempting to remove that, so I figured I'd come back to it later instead.
There is one fairly major change in this pull, and it's moving from native stdio to uv stdio via `print` and `println`. Unfortunately logging still goes through native I/O (via `dumb_println`). This is going to need some thinking, because I still want the goal of logging/printing to be 0 allocations, and this is not possible if `io::stdio::stderr()` is called on each log message. Instead I think that this may need to be cached as the `logger` field inside the `Task` struct, but that will require a little more workings to get right (this is also a similar problem for print/println, do we cache `stdout()` to not have to re-create it every time?).

The minimum (negative) value of a float is `-Bounded::max_value()`, not `Bounded::min_value()`.
Otherwise the following has an incorrect behavior:
```rust
let a = -1.0f64;
let b: f32 = NumCast::from(a); // incorrectly returns None
```
This changes an `assert_once_ever!` assertion to just a plain old assertion
around an atomic boolean to ensure that one particular runtime doesn't attempt
to exit twice.
