41da875fae Add Option::as_slice(_mut)
This adds the following functions:

* `Option<T>::as_slice(&self) -> &[T]`
* `Option<T>::as_slice_mut(&mut self) -> &[T]`

The `as_slice` and `as_slice_mut` functions benefit from an
optimization that makes them completely branch-free.

Note that the optimization's soundness hinges on the fact that either
the niche optimization makes the offset of the `Some(_)` contents zero
or the mempory layout of `Option<T>` is equal to that of
`Option<MaybeUninit<T>>`.

Inline `Poll` methods

With `opt-level="z"`, the `Poll::map*` methods are sometimes not inlined (see <https://godbolt.org/z/ca5ajKTEK>). This PR adds `#[inline]` to these methods. I have a project that can benefit from this change, but do we want to enable this behavior universally?

Fixes #101080.

Stabilize `#![feature(target_feature_11)]`

## Stabilization report

### Summary

Allows for safe functions to be marked with `#[target_feature]` attributes.

Functions marked with `#[target_feature]` are generally considered as unsafe functions: they are unsafe to call, cannot be assigned to safe function pointers, and don't implement the `Fn*` traits.

However, calling them from other `#[target_feature]` functions with a superset of features is safe.

```rust
// Demonstration function
#[target_feature(enable = "avx2")]
fn avx2() {}

fn foo() {
    // Calling `avx2` here is unsafe, as we must ensure
    // that AVX is available first.
    unsafe {
        avx2();
    }
}

#[target_feature(enable = "avx2")]
fn bar() {
    // Calling `avx2` here is safe.
    avx2();
}
```

### Test cases

Tests for this feature can be found in [`src/test/ui/rfcs/rfc-2396-target_feature-11/`](b67ba9ba20/src/test/ui/rfcs/rfc-2396-target_feature-11/).

### Edge cases

- https://github.com/rust-lang/rust/issues/73631

Closures defined inside functions marked with `#[target_feature]` inherit the target features of their parent function. They can still be assigned to safe function pointers and implement the appropriate `Fn*` traits.

```rust
#[target_feature(enable = "avx2")]
fn qux() {
    let my_closure = || avx2(); // this call to `avx2` is safe
    let f: fn() = my_closure;
}
```

This means that in order to call a function with `#[target_feature]`, you must show that the target-feature is available while the function executes *and* for as long as whatever may escape from that function lives.

6290ae92b2 Auto merge of #108487 - cjgillot:no-typeck-mir, r=oli-obk
Avoid invoking typeck from borrowck

This PR attempts to reduce direct dependencies between typeck and MIR-related queries. The goal is to have all the information transit either through THIR or through dedicated queries that avoid depending on the whole `TypeckResults`.

In a first commit, we store the type information that MIR building requires into THIR. This avoids edges between mir_built and typeck.

In the second and third commit, we wrap informations around closures (upvars, kind origin and user-provided signature) to avoid borrowck depending on typeck information.

There should be a single remaining borrowck -> typeck edge in the good path, due to inline consts.

Lazy norm is hard.

`<?0 as Trait>::Assoc = ?0` ... probably should emit an alias-eq goal, but currently we don't do that. Right now it fails with a cyclical ty error.

Also committed a check-pass test that broken when I attempted to fix this (unsuccessfully).

Move IpAddr, SocketAddr and V4+V6 related types to `core`

Implements RFC https://github.com/rust-lang/rfcs/pull/2832. The RFC has completed FCP with disposition merge, but is not yet merged.

Moves IP types to `core` as specified in the RFC.

The full list of moved types is: `IpAddr`, `Ipv4Addr`, `Ipv6Addr`, `SocketAddr`, `SocketAddrV4`, `SocketAddrV6`, `Ipv6MulticastScope` and `AddrParseError`.

Doing this move was one of the main driving arguments behind #78802.
