801bc48939 Rewrite Unique<T> so that it is covariant in T, implies NonZero and ownership,
and also follows the API of `NonZero` a bit more closely. More to do
here I think (including perhaps a new name).

2594d56e32 Introduce the new phantomdata/phantomfn markers and integrate them
into variance inference; fix various bugs in variance inference
so that it considers the correct set of constraints; modify infer to
consider the results of variance inference for type arguments.

7412d1b2ef Eliminate excessive null-checks from slice iterators
The data pointer used in the slice is never null, using assume() to tell
LLVM about it gets rid of various unneeded null checks when iterating
over the slice.

Since the snapshot compiler is still using an older LLVM version, omit
the call in stage0, because compile times explode otherwise.

52b5150cfd Avoid ptrtoint when checking if a pointer is null
Casting the pointer to an integer requires a ptrtoint, while casting 0
to a pointer is directly folded to a `null` value.

An "immutable reference-counted pointer" is confusing, one might think that the `Rc` itself is immutable which isn't the case.

f807b6a61e rollup merge of #22440: semarie/openbsd-connect_error
The `connect_error` test check if connecting to "0.0.0.0:1" works (it
shouldn't). And in case of error, the test expects a `ConnectionRefused`
error.

Under OpenBSD, trying to connect to "0.0.0.0" isn't a `ConnectionRefused`:
it is an `InvalidInput` error.

The patch allow the error to be `ConnectionRefused` or `InvalidInput`.

Another possibility is to check connecting to "127.0.0.1:1" and expects only `ConnectionRefused` error.

eca2453a02 rollup merge of #22208: aturon/expose-more-path
This commit exposes the `is_sep` function and `MAIN_SEP` constant, as
well as Windows path prefixes. The path prefix enum is safely exposed on
all platforms, but it only yielded as a component for Windows.

Exposing the prefix enum as part of prefix components involved changing
the type from `OsStr` to the `Prefix` enum, which is a:

f492095eb4 rollup merge of #22024: alexcrichton/ascii
* Move the type parameter on the `AsciiExt` trait to an associated type named
  `Owned`.
* Move `ascii::escape_default` to using an iterator.

This is a breaking change due to the removal of the type parameter on the
`AsciiExt` trait as well as the modifications to the `escape_default` function
to returning an iterator. Manual implementations of `AsciiExt` (or `AsciiExt`
bounds) should be adjusted to remove the type parameter and using the new
`escape_default` should be relatively straightforward.

d8f8f7a58c Revise std::thread semantics
This commit makes several changes to `std::thread` in preparation for
final stabilization:

* It removes the ability to handle panics from `scoped` children; see
  #20807 for discussion

* It adds a `JoinHandle` structure, now returned from `spawn`, which
  makes it possible to join on children that do not share data from
  their parent's stack. The child is automatically detached when the
  handle is dropped, and the handle cannot be copied due to Posix
  semantics.

* It moves all static methods from `std:🧵:Thread` to free
  functions in `std::thread`. This was done in part because, due to the
  above changes, there are effectively no direct `Thread` constructors,
  and the static methods have tended to feel a bit awkward.

* Adds an `io::Result` around the `Builder` methods `scoped` and
  `spawn`, making it possible to handle OS errors when creating
  threads. The convenience free functions entail an unwrap.

* Stabilizes the entire module. Despite the fact that the API is
  changing somewhat here, this is part of a long period of baking and
  the changes are addressing all known issues prior to alpha2. If
  absolutely necessary, further breaking changes can be made prior to beta.

Closes #20807
