7afface3ff extra: Implement .rev_iter() in treemap 
Implement reverse iterators for TreeMap and TreeSet, that produce the
keys in backward order.

52b01c50cb extra: External iterators for TreeSet set operations 
Write external iterators for Difference, Sym. Difference, Intersection
and Union set operations.

These iterators are generic insofar that they could work on any ordered
sequence iterators, even though they are type specialized to the
TreeSetIterator in this case.

Looking at the `check` function in the treeset tests, rustc seems
unwilling to compile a function resembling::

    fn check<'a, T: Iterator<&'a int>>(... )

so the tests for these iterators are still running the legacy loop
protocol.

98ec79c957 auto merge of #8294 : erickt/rust/map-move, r=bblum 
According to #7887, we've decided to use the syntax of `fn map<U>(f: &fn(&T) -> U) -> U`, which passes a reference to the closure, and to `fn map_move<U>(f: &fn(T) -> U) -> U` which moves the value into the closure. This PR adds these `.map_move()` functions to `Option` and `Result`.

In addition, it has these other minor features:
 
* Replaces a couple uses of `option.get()`, `result.get()`, and `result.get_err()` with `option.unwrap()`, `result.unwrap()`, and `result.unwrap_err()`. (See #8268 and #8288 for a more thorough adaptation of this functionality.
* Removes `option.take_map()` and `option.take_map_default()`. These two functions can be easily written as `.take().map_move(...)`.
* Adds a better error message to `result.unwrap()` and `result.unwrap_err()`.

The two deletions are because the test cases are very old (still using `class` and modes!), and, as far as I can tell (since they are so old), the areas they test are well tested by other rpass tests.

4da1cfe923 auto merge of #8285 : huonw/rust/deriving+++, r=alexcrichton 
Some general clean-up relating to deriving:
- `TotalOrd` was too eager, and evaluated the `.cmp` call for every field, even if it could short-circuit earlier.
- the pointer types didn't have impls for `TotalOrd` or `TotalEq`.
- the Makefiles didn't reach deep enough into libsyntax for dependencies.

(Split out from https://github.com/mozilla/rust/pull/8258.)

62dbdc4ea2 auto merge of #8287 : sfackler/rust/hex, r=alexcrichton 
FromHex ignores whitespace and parses either upper or lower case hex
digits. ToHex outputs lower case hex digits with no whitespace. Unlike
ToBase64, ToHex doesn't allow you to configure the output format. I
don't feel that it's super useful in this case.

55f3d04101 vec: use offset_inbounds for iterators 
This allows LLVM to optimize vector iterators to an `getelementptr` and
`icmp` pair, instead of `getelementptr` and *two* comparisons.

~~~
fn foo(xs: &mut [f64]) {
    for x in xs.mut_iter() {
        *x += 10.0;
    }
}

f23fb19ee5 vec: avoid ptrtoint/inttoptr in the iterators 
This results in throwing away alias analysis information, because LLVM
does *not* implement reasoning about these conversions yet.

We specialize zero-size types since a `getelementptr` offset will
return us the same pointer, making it broken as a simple counter.

8f9bbc476d remove extra::iter 
This module provided adaptors for the old internal iterator protocol,
but they proved to be quite unreadable and are not generic enough to
handle borrowed pointers well.

Since Rust no longer defines an internal iteration protocol, I don't
think there's going to be any reuse via these adaptors.
