Added the `Option::unzip()` method
* Adds the `Option::unzip()` method to turn an `Option<(T, U)>` into `(Option<T>, Option<U>)` under the `unzip_option` feature
* Adds tests for both `Option::unzip()` and `Option::zip()`, I noticed that `.zip()` didn't have any
* Adds `#[inline]` to a few of `Option`'s methods that were missing it
Constify implementations of `(Try)From` for int types
I believe this to be one of the (many?) things blocking const (Range) iterators.
~~If this is to be merged maybe that should wait until `#![feature(const_trait_impl)]` no longer needs `#![allow(incomplete_features)]`?~~ - Done
Clean up examples in new lint suggestion template
I'm pretty sure they meant to write `bounds checking` when they wrote `bounce checking` but I could be wrong. After that I thought I could improve it further and ended up with this.
changelog: none
Cleanup usage of `span_to_snippet` and `LintContext::sess`
- avoid using `SourceMap::span_to_snippet` directly and use `clippy_utils::source::snippet_opt` instead
- don't use `LintContext::sess()` on `EarlyContext`s which have a `sess` field directly available, saving the import of `LintContext`
changelog: none
Replace read_to_string with read_line in Stdin example
The current example results in infinitely reading from stdin, which can confuse newcomers trying to read from stdin.
(`@razmag` encountered this while learning the language from the docs)
* This commit adds the aarch64-unknown-uefi target and also adds it into
the supported targets list under the tier-3 target table.
* Uses the small code model by default

Fix feature gate checking of static-nobundle and native_link_modifiers
Feature native_link_modifiers_bundle don't need feature static-nobundle
to work.
Also check the feature gates when using native_link_modifiers from command line options. Current nighly compiler don't check those feature gate.

Simplify typeck/primary_body_of, fix comment to match return signature
Hi, new contributor here! I'm carefully reading through the various modules just to learn. I noticed this function, `primary_body_of`, which has gone through a couple of refactors over time, adding new `Option`s to its returned tuple. Observations:
1. the `fn`'s documentation was not all up to date with the the current return signature.
2. `FnHeader` and `FnDecl` are always both `Some` or `None`. So I figured it might just return a reference to the full `hir::FnSig`, for simplicity and more precise typing. It's a pure refactor.
I'm learning better by working with code than just reading it, so here goes! If you want to avoid pure refactor PRs that don't really fix anything, I can revert the code change to only update the comment instead.
Stabilize Vec<T>::shrink_to
This PR stabilizes `shrink_to` feature and closes the corresponding issue. The second point was addressed already, and no `panic!` should occur.
Closes#56431.
