Allow using `clippy::msrv` as an outer attribute

changelog: Allow specifying `#[clippy::msrv]` as an outer attribute

Probably not too useful to clippy users, but it makes the MSRV tests slightly cleaner

Re-enable `uninlined_format_args` on multiline `format!`

fix https://github.com/rust-lang/rust-clippy/issues/9719

There was an issue with the code suggestion which can be sometimes completely broken (fortunately when applied it's valid), so we do not show it.

changelog: [`uninlined_format_args`] re-enable for multiline format expression, but do not show the literal code suggestion in those cases

Lint unnecessary safety comments

changelog: [`unnecessary_safety_comment`]: Add unnecessary safety comment lint

Addresses https://github.com/rust-lang/rust-clippy/issues/7954

This does not necessarily catch all occurences, as doing so would require checking all expressions in the entire source which seems rather expensive. Instead what the lint does is it checks items, statements and the tail expression of blocks for safety comments, then checks if those comments are necessary or not, then linting for the unnecessary ones.

I kept the tests in one file to check that the lints do not clash with each other.

2ad5e486f6 Auto merge of #103693 - HKalbasi:master, r=oli-obk
Make rustc_target usable outside of rustc

I'm working on showing type size in rust-analyzer (https://github.com/rust-lang/rust-analyzer/pull/13490) and I currently copied rustc code inside rust-analyzer, which works, but is bad. With this change, I would become able to use `rustc_target` and `rustc_index` directly in r-a, reducing the amount of copy needed.

This PR contains some feature flag to put nightly features behind them to make crates buildable on the stable compiler + makes layout related types generic over index type + removes interning of nested layouts.

300d10fb99 Auto merge of #104321 - Swatinem:async-gen, r=oli-obk
Avoid `GenFuture` shim when compiling async constructs

Previously, async constructs would be lowered to "normal" generators, with an additional `from_generator` / `GenFuture` shim in between to convert from `Generator` to `Future`.

The compiler will now special-case these generators internally so that async constructs will *directly* implement `Future` without the need to go through the `from_generator` / `GenFuture` shim.

The primary motivation for this change was hiding this implementation detail in stack traces and debuginfo, but it can in theory also help the optimizer as there is less abstractions to see through.

---

Given this demo code:

```rust
pub async fn a(arg: u32) -> Backtrace {
    let bt = b().await;
    let _arg = arg;
    bt
}

pub async fn b() -> Backtrace {
    Backtrace::force_capture()
}
```

I would get the following with the latest stable compiler (on Windows):

```
   4: async_codegen:🅱️:async_fn$0
             at .\src\lib.rs:10
   5: core::future::from_generator::impl$1::poll<enum2$<async_codegen:🅱️:async_fn_env$0> >
             at /rustc/897e37553bba8b42751c67658967889d11ecd120\library\core\src\future\mod.rs:91
   6: async_codegen:🅰️:async_fn$0
             at .\src\lib.rs:4
   7: core::future::from_generator::impl$1::poll<enum2$<async_codegen:🅰️:async_fn_env$0> >

```

whereas now I get a much cleaner stack trace:

```
   3: async_codegen:🅱️:async_fn$0
             at .\src\lib.rs:10
   4: async_codegen:🅰️:async_fn$0

Fix [`unnecessary_lazy_eval`] when type has significant drop

fix for https://github.com/rust-lang/rust-clippy/issues/9427#issuecomment-1295742590

However current implementation gives too many false positive, rending the lint almost useless.

I don't know what's the best way to check if a type has a "significant" drop (in the common meaning, not the internal rustc one, for example Option<(u8, u8)> should not be considered significant)

Fix #9771 (`unnecessary_to_owned` false positive)

Fixes #9771

In that issue's example(s), the lint tried to add a `&` to a value, which implicitly changed the type of a field to a reference. The fix is to add the reference to `receiver_ty` (the type of the receiver of the `to_owned`-like method), before passing `receiver_ty` to `can_change_type`. `can_change_type` properly rejects the modified `receiver_ty`.

cc: `@mikerite` just because I think he was the author of `can_change_type`.
