413540837b Auto merge of #3108 - RalfJung:dlsym, r=RalfJung 
refactor dlsym: dispatch symbols via the normal shim mechanism

This avoids having to adjust Miri when switching between invoking the function via a linked symbol vs via dlsym.

10ab51d69d Sort rustc_driver_impl dependencies. 
As per
https://github.com/rust-lang/rust/blob/master/src/doc/style-guide/src/cargo.md,
which says:

> Sort key names alphabetically within each section, with the exception
> of the [package] section.

And use tidy to enforce it.

Don't restrict it to lines that have `//` in them. This means it can be
used in `Cargo.toml` files, for example.

f9003c08ab Auto merge of #3098 - BlackHoleFox:apple-entropy, r=RalfJung 
Support getentropy on macOS as a foreign item

Prior this was always assumed to be accessed via `dlsym` shim, but in `std` I'm attempting to start [unconditionally linking](https://github.com/rust-lang/rust/pull/116319) to `getentropy` on macOS now that Rust's platform version support allows it.

This just moves the main logic of the previous `dlsym` handler into an eval context extension so it can be used via both call paths. The `dlsym` handler is still needed as `getrandom` uses it.

Rollup merge of #116421 - Urgau:inter-mut-invalid_ref_casting, r=oli-obk 
Clarify `invalid_reference_casting` lint around interior mutable types

This is PR intends to clarify the `invalid_reference_casting` lint around interior mutable types by adding a note for them saying that they should go through `UnsafeCell::get`.

So for this code:
```rust
let cell = &std::cell::UnsafeCell::new(0);
let _num = &mut *(cell as *const _ as *mut i32);
```

the following note will be added to the lint output:

```diff
 error: casting `&T` to `&mut T` is undefined behavior, even if the reference is unused,  consider instead using an `UnsafeCell`
   --> $DIR/reference_casting.rs:68:16
    |
 LL |     let _num = &mut *(cell as *const _ as *mut i32);
    |                ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    |
    = note: for more information, visit <https://doc.rust-lang.org/book/ch15-05-interior-mutability.html>
+   = note: even for types with interior mutability, the only legal way to obtain a mutable pointer from a shared reference is through `UnsafeCell::get`
```

Suggestion are welcome around the note contents.

Remove libc

We don't use much libc on Windows and it seemed silly to keep if for the sake of [two well documented constants](https://learn.microsoft.com/en-us/cpp/c-runtime-library/exit-success-exit-failure?view=msvc-170).

2c9b0de8ea Auto merge of #116269 - Veykril:rustc-abi, r=WaffleLapkin 
Bring back generic parameters for indices in rustc_abi and make it compile on stable

This effectively reverses https://github.com/rust-lang/rust/pull/107163, allowing rust-analyzer to depend on this crate again,

It also moves some glob imports / expands them in the first commit because they made it more difficult for me to reason about things.

ad8271dd56 Use collect to decode Vec. 
It's hyper-optimized, we don't need our own unsafe code here.

This requires getting rid of all the `Allocator` stuff, which isn't
needed anyway.

5f69ca62f2 rustc_serialize: merge collection_impls.rs into serialize.rs. 
`serialize.rs` has the `Encodable`/`Decodable` impls for lots of basic
types, including `Vec`. `collection_impls` has it for lots of collection
types. The distinction isn't really meaningful, and it's simpler to have
them all in a single file.
