520461f1fb Provide suggestions for some moved value errors
When encountering an used moved value where the previous move happened
in a `match` or `if let` pattern, suggest using `ref`. Fix #63988.

When encountering a `&mut` value that is used in multiple iterations of
a loop, suggest reborrowing it with `&mut *`. Fix #62112.

Rollup merge of #73698 - spastorino:patch-1, r=wesleywiser
Add procedure for prioritization notifications on Zulip

This PR was originally opened by @LeSeulArtichaut as #73695, closing that one in favor of this one. Made some slight changes to it but can't push to @LeSeulArtichaut branch.

Add UI test for issue 73592

It happens that #72280 accidentally fixed a bug which is later discovered in #73592. This PR adds a UI test to prevent future regression.

Closes #73592

Rollup merge of #73516 - Crabapple-iOS:feature/apple-dynamic-linking, r=nikomatsakis
Allow dynamic linking for iOS/tvOS targets

During the development and testing of the [Crabapple project](https://github.com/Crabapple-iOS/Crabapple), one obstacle was the lack of `cdylib` target support for iOS. Surprisingly, once `dynamic_linking` was enabled for iOS targets, it worked seemingly flawlessly.

I could not find any information on why this was initially or still is disabled.

Rollup merge of #72700 - davidtwco:issue-66220-improper-ctypes-declarations, r=lcnr,varkor
`improper_ctypes_definitions` lint

Addresses #19834, #66220, and #66373.

This PR takes another attempt at #65134 (reverted in #66378). Instead of modifying the existing `improper_ctypes` lint to consider `extern "C" fn` definitions in addition to `extern "C" {}` declarations, this PR adds a new lint - `improper_ctypes_definitions` - which only applies to `extern "C" fn` definitions.

In addition, the `improper_ctype_definitions` lint differs from `improper_ctypes` by considering `*T` and `&T` (where `T: Sized`) FFI-safe (addressing #66220).

There wasn't a clear consensus in #66220 (where the issues with #65134 were primarily discussed) on the approach to take, but there has [been some discussion in Zulip](https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/.2366220.20improper_ctypes.20definitions.20vs.20declarations/near/198903086). I fully expect that we'll want to iterate on this before landing.

8f40dae93b Suggest type param trait bound for binop only when appropriate
Verify that the binop trait *is* implemented for the types *if* all the
involved type parameters are replaced with fresh inferred types. When
this is the case, it means that the type parameter was indeed missing a
trait bound. If this is not the case, provide a generic `note` refering
to the type that doesn't implement the expected trait.

Implement associated lang items
Fixes #70718

This commit allows making associated items (e.g. associated functions
and types) into lang items via the `#[lang]` attribute. This allows such
items to be accessed directly, rather than by iterating over the parent
item's associated items.

I've added `FnOnce::Output` as a lang item, and updated one old usage to
use the new lang item. The remaining uses can be updated separately.

Add re-exports to use suggestions

In the following example, an inaccessible path is suggested via `use foo::bar::X;` whereas an accessible public exported path can be suggested instead.

```rust
mod foo {
    mod bar {
        pub struct X;
    }
    pub use self::bar::X;
}

fn main() { X; }
```

This fixes the issue.

Rollup merge of #73639 - ayazhafiz:i/73553, r=davidtwco
Change heuristic for determining range literal

Currently, rustc uses a heuristic to determine if a range expression is
not a literal based on whether the expression looks like a function call
or struct initialization. This fails for range literals whose
lower/upper bounds are the results of function calls. A possibly-better
heuristic is to check if the expression contains `..`, required in range
literals.

Of course, this is also not perfect; for example, if the range
expression is a struct which includes some text with `..` this will
fail, but in general I believe it is a better heuristic.

A better alternative altogether is to add the `QPath::LangItem` enum
variant suggested in #60607. I would be happy to do this as a precursor
to this patch if someone is able to provide general suggestions on how
usages of `QPath` need to be changed later in the compiler with the
`LangItem` variant.

improper_ctypes: only allow params in defns mode
This commit adjusts the behaviour introduced in a previous commit so
that generic parameters and projections are only allowed in the
definitions mode - and are otherwise a bug. Generic parameters in
declarations are prohibited earlier in the compiler, so if that branch
were reached, it would be a bug.
