1. Use next_back for last.
2. Use slices for computing nth. It might be possible to use the same
code for both the mut/const case but I don't know how that will play
with compiler optimizations.
`ToCStr` was removed with `old_io` and the current method `as_os_str`
is inherent to `Path`, meaning there is no suitable trait bound that
could be used here.
Two more chapters of TRPL. The `type` one is pretty straightforward, but I wasn't really sure what to put for unsized types. I just explained the very basics, and the special bounds syntax. Thoughts on what else should go here?

Much of this code hasn't been updated in quite some time and this commit does a
small audit of the functionality:
* Implementation functions now centralize all functionality on a locally defined
`Thread` type.
* The `detach` method has been removed in favor of a `Drop` implementation. This
notably fixes leaking thread handles on Windows.
* The `Thread` structure is now appropriately annotated with `Send` and `Sync`
automatically on Windows and in a custom fashion on Unix.
* The unsafety of creating a thread has been pushed out to the right boundaries
now.
Closes#24442

Instead of rustc-1.0.0-beta-$triple.tar.gz, betas will be named
rustc-beta-$triple.tar.gz. This will give betas a stable download
URL, prevent old artifacts from accumulating in the dist server's
root directory, and not require the website to be updated every
beta.
As a tradeoff, it will be harder to download previous betas because
they will need to be located in the archives.
This is an implementation of [RFC 1030][rfc] which adds these traits to the
prelude and additionally removes all inherent `into_iter` methods on collections
in favor of the trait implementation (which is now accessible by default).

This is technically a breaking change due to the prelude additions and removal
of inherent methods, but it is expected that essentially no code breaks in
practice.

Closes#24538
The documentation doesn't appear to describe the `&foo[..]` syntax.
I tried looking in `primitive-types.html#slices` and `std/primitive.slice.html`.
There's an example of partially slicing an array in trpl and a mention of `&foo[..]` in [the standard library documentation](https://doc.rust-lang.org/std/primitive.slice.html), but neither place, from what I can see, actually describes the behavior of `&foo[..]`.

as accepted in [RFC 526](https://github.com/rust-lang/rfcs/blob/master/text/0526-fmt-text-writer.md).
Note that this brand new method is marked as **stable**. I judged this safe enough: it’s simple enough that it’s very unlikely to change. Still, I can mark it unstable instead if you prefer.

For now, words() is left in (but deprecated), and Words is a type alias for
struct SplitWhitespace.
Also cleaned up references to str.words() throughout codebase.
Closes#15628
This removes the usage of `#[feature(into_cow, slice_patterns, box_syntax, box_patterns, quote, unsafe_destructor)]` from being used in libsyntax. My main desire for this is that it brings me one step closer to letting [syntex](https://github.com/erickt/rust-syntex) compile with stable rust. Hopefully this doesn't inconvenience rust development.
