32d962d16f Auto merge of #31420 - bluss:deque-equality, r=Gankro
collections: Use slice parts in PartialEq for VecDeque

This improves == for VecDeque by using the slice representation.

This will also improve further if codegen for slice comparison improves.

Benchmark run of 1000 u64 elements, comparing for equality (all equal).
Cpu time to compare the vecdeques is reduced to less than 50% of what it
was before.

```
test test_eq_u64       ... bench:  1,885 ns/iter (+/- 163) = 4244 MB/s
test test_eq_new_u64   ... bench:    802 ns/iter (+/- 100) = 9975 MB/s
```

523fa1331e Auto merge of #31494 - alexcrichton:ar-gnu-by-default, r=brson
The compiler currently vendors its own version of "llvm-ar" (not literally the
binary but rather the library support) and uses it for all major targets by
default (e.g. everything defined in `src/librustc_back/target`). All custom
target specs, however, still search for an `ar` tool by default. This commit
changes this default behavior to using the internally bundled llvm-ar with the
GNU format.

Currently all targets use the GNU format except for OSX which uses the BSD
format (surely makes sense, right?), and custom targets can change the format
via the `archive-format` key in custom target specs.

I suspect that we can outright remove support for invoking an external `ar`
utility, but I figure for now there may be some crazy target relying on that so
we should leave support in for now.

0542745768 Auto merge of #31438 - aturon:stab-ip-addr, r=alexcrichton
After [considerable pushback](https://github.com/rust-lang/rfcs/issues/1451), it's clear that there is a community consensus around providing `IpAddr` in the standard library, together with other APIs using it.

This commit reverts from deprecated status directly to stable. The deprecation landed in 1.6, which has already been released, so the stabilization is marked for 1.7 (currently in beta; will require a backport).

fc1c1183f3 Auto merge of #31510 - dikaiosune:master, r=bluss
Since a lexicographic ordering of a struct could vary based on which struct members are compared first, I ended up doing some testing to ensure that the behavior when deriving these traits was what I expected (ordered based on the top to bottom order of declaration of the members). I wanted to add this little bit of documentation to potentially save someone else the same effort. That is, assuming that my testing correctly reflects the intended behavior of the compiler.

This commit fixes the docs do both be more accurate and to explain why
the return type is a Cow<'a, str>.

f8fa6140fa Auto merge of #31397 - bradfirj:arc-docfix, r=steveklabnik
The documentation for the `make_mut` function on `Arc<T>` contains a somewhat impenetrable double-negative that I was only able to fully grasp by looking at the implementation. Here's a quick rewrite that reads a lot better.

The sentence "doesn't have one strong reference and no weak references." is a
hard to understand, and it can be much more easily explained. In particular, such a double-negative
could give English as a Second Language users even more trouble than native speakers.
