279a780804 auto merge of #15983 : brson/rust/fail, r=alexcrichton 
A few refactorings to decrease text size and increase data size. I'm not sure about this tradeoff. Various stats below. cc @pcwalton

This reduces the code needed to pass arguments for `fail!()`, `fail!("{}", ...)`, and to a lesser extent `fail!("...")`. Still more work to be done on compiler-generated failures and the `fail!("...")` case.

do_fail_empty:

```
#[inline(never)]
fn do_fail_empty() {
    fail!()
}
```

do_fail_empty before:

```
	leaq	8(%rsp), %rdi
	movabsq	$13, %rsi
	leaq	"str\"str\"(1494)"(%rip), %rax
	movq	%rax, 8(%rsp)
	movq	$19, 16(%rsp)
	callq	_ZN6unwind31begin_unwind_no_time_to_explain20h57030457935ab6111SdE@PLT
```

do_fail_empty after:

	callq	_ZN6unwind31begin_unwind_no_time_to_explain20h33184cfdcce4dfd8QTdE@PLT
```

do_fail_fmt:

```
#[inline(never)]
fn do_fail_fmt() {
    fail!("guh{}", "faw")
}
```

do_fail_fmt before:

```

File size increases.

Text size decreases by 52486 while data size increases by 143686.

I don't know if anything can be learned from these benchmarks. Looks like a wash.

caa564bea3 librustc: Stop desugaring for expressions and translate them directly. 
This makes edge cases in which the `Iterator` trait was not in scope
and/or `Option` or its variants were not in scope work properly.

This breaks code that looks like:

    struct MyStruct { ... }

    impl MyStruct {
        fn next(&mut self) -> Option<int> { ... }
    }

    for x in MyStruct { ... } { ... }

Change ad-hoc `next` methods like the above to implementations of the
`Iterator` trait. For example:

    impl Iterator<int> for MyStruct {
        fn next(&mut self) -> Option<int> { ... }
    }

Closes #15392.

ba707fb3a0 Remove OwnedStr trait 
This trait was only implemented by `String`. It provided the methods
`into_bytes` and `append`, both of which **are already implemented as normal
methods** of `String` (not as trait methods). This change improves the
consistency of strings.

This shouldn't break any code, except if somebody has implemented
`OwnedStr` for a user-defined type.

Summary:

* alloc::rc module stable
* Rc type stable
* Functions relating to weak references experimental
* core::cmp module stable
* PartialEq/Eq/PartialOrd/Ord unstable because trait reform will make them change again
* Equiv experimental because there may be better sol'ns
* lexical_ordering deprecated because it can be done trivially with the Ord trait
* min/max stable
* std::task module stable
* TaskBuilder::stdout/stderr experimental because we aren't certain we want to configure the environment this way
* try_future experimental because Future is experimental
* try unstable because the error type might change
* deschedule/failing unstable

The major thing I did differently than previously-discussed is that I made `try` experimental: there's been discussion that the error type `Box<Any + Send>` is not sufficient.

- `width()` computes the displayed width of a string, ignoring the width of control characters.
    - arguably we might do *something* else for control characters, but the question is, what?
    - users who want to do something else can iterate over chars()

- `graphemes()` returns a `Graphemes` struct, which implements an iterator over the grapheme clusters of a &str.
    - fully compliant with [UAX#29](http://www.unicode.org/reports/tr29/#Grapheme_Cluster_Boundaries)
    - passes all [Unicode-supplied tests](http://www.unicode.org/reports/tr41/tr41-15.html#Tests29)

- added code to generate additionial categories in `unicode.py`
    - `Cn` aka `Not_Assigned`
    - categories necessary for grapheme cluster breaking

- tidied up the exports from libunicode
  - all exports are exposed through a module rather than directly at crate root.
  - std::prelude imports UnicodeChar and UnicodeStrSlice from std::char and std::str rather than directly from libunicode

cf432b8f8f add Graphemes iterator; tidy unicode exports 
- Graphemes and GraphemeIndices structs implement iterators over
  grapheme clusters analogous to the Chars and CharOffsets for chars in
  a string. Iterator and DoubleEndedIterator are available for both.

- tidied up the exports for libunicode. crate root exports are now moved
  into more appropriate module locations:
  - UnicodeStrSlice, Words, Graphemes, GraphemeIndices are in str module
  - UnicodeChar exported from char instead of crate root
  - canonical_combining_class is exported from str rather than crate root

Since libunicode's exports have changed, programs that previously relied
on the old export locations will need to change their `use` statements
to reflect the new ones. See above for more information on where the new
exports live.
