9c7c232a50 Improve FromStr example 
The `from_str` implementation from the example had an `unwrap` that would make it panic on invalid input strings. Instead of panicking, it nows returns an error to better reflect the intented behavior of the `FromStr` trait.

c2590e6e89 Auto merge of #102535 - scottmcm:optimize-split-at-partition-point, r=thomcc 
Tell LLVM that `partition_point` returns a valid fencepost

This was already done for a successful `binary_search`, but this way `partition_point` can get similar optimizations.

Demonstration that nightly can't do this optimization today, and leaves in the panicking path: <https://play.rust-lang.org/?version=nightly&mode=release&edition=2021&gist=e1074cd2faf5f68e49cffd728ded243a>

609152aa8a Rollup merge of #102342 - jmillikin:nonzero-negation, r=scottmcm 
Add negation methods for signed non-zero integers.

Performing negation with defined wrapping semantics (such as `wrapping_neg()`) on a non-zero integer currently requires unpacking to a primitive and re-wrapping. Since negation of non-zero signed integers always produces a non-zero result, it is safe to implement the various `*_neg()` methods for `NonZeroI{N}`.

I'm not sure what to do about the `#[unstable(..., issue = "none")]` here -- should I file a tracking issue, or is that handled by the Rust dev team?

8e4869e862 Rollup merge of #102368 - beetrees:nano-niche, r=joshtriplett 
Add a niche to `Duration`, unix `SystemTime`, and non-apple `Instant`

As the nanoseconds fields is always between `0` and `(NANOS_PER_SEC - 1)` inclusive, use the `rustc_layout_scalar_valid_range` attributes to create a niche in the nanosecond field of `Duration` and `Timespec` (which is used to implement unix `SystemTime` and non-apple unix `Instant`; windows `Instant` is implemented with `Duration` and therefore will also benefit). This change has the benefit of making `Option<T>` the same size as `T` for the previously mentioned types. Also shrinks the nanoseconds field of `Timespec` to a `u32` as nanoseconds do not need the extra range of an `i64`, shrinking `Timespec` by 4 bytes on 32-bit platforms.

ce7f0f1aa0 Auto merge of #100719 - CohenArthur:rust-safe-intrinsic-attribute, r=wesleywiser 
Add `#[rustc_safe_intrinsic]`

This PR adds the `#[rustc_safe_intrinsic]` attribute as mentionned on Zulip. The goal of this attribute is to avoid keeping a list of symbols as the source for stable intrinsics, and instead rely on an attribute. This is similar to `#[rustc_const_stable]` and `#[rustc_const_unstable]`, which among other things, are used to mark the constness of intrinsic functions.

Suggest unwrapping `???<T>` if a method cannot be found on it but is present on `T`.

This suggests various ways to get inside wrapper types if the method cannot be found on the wrapper type, but is present on the wrappee.

For this PR, those wrapper types include `Localkey`, `MaybeUninit`, `RefCell`, `RwLock` and `Mutex`.

The doc comment for [splitn](https://github.com/rust-lang/rust/blob/master/library/core/src/slice/mod.rs#L2051:L2056) is the exact same as the comment for [splitn_mut](https://github.com/rust-lang/rust/blob/master/library/core/src/slice/mod.rs#L2079:L2084).  The doc comment for `splitn_mut` should instead say it's working on a mutable subslice.
