Steve Klabnik 6ac7fc73f5 Update infrastructure for fail -> panic
This includes updating the language items and marking what needs to
change after a snapshot.

If you do not use the standard library, the language items you need to
implement have changed. For example:

```rust
 #[lang = "fail_fmt"] fn fail_fmt() -> ! { loop {} }
```

is now

```rust
 #[lang = "panic_fmt"] fn panic_fmt() -> ! { loop {} }
```

Related, lesser-implemented language items `fail` and
`fail_bounds_check` have become `panic` and `panic_bounds_check`, as
well. These are implemented by `libcore`, so it is unlikely (though
possible!) that these two renamings will affect you.

[breaking-change]
