Clone the `src/llvm-project` submodule if profiling is enabled
To compile rustc with profiling information, `compiler-rt` from LLVM is required. Building it requires the `src/llvm-project` submodule to be initialized and updated.

Update mentions to `rustc_metadata::rmeta::Lazy`
While working on https://github.com/rust-lang/rustc-dev-guide/pull/1411, I noticed there are still some mentions of `Lazy`. This updates them to `LazyValue`, `LazyArray`, or `LazyTable`.

Htmldocck: Substitute the doc channel when blessing
Since #84942, the snippet `{{channel}}` gets substituted with the concrete “doc channel” (e.g. `https://doc.rust-lang.org/nightly`) when snapshot files are checked against the actual rustdoc output.
However, when you `--bless` rustdoc tests, htmldocck just dumps the concrete channel into the snapshot file and
you have to manually do a find-and-replace after blessing to uphold what #84942 set out to fix.
I admit it's a bit fragile to blindly replace URLs like this but I guess it's not too bad in practice.
Feel free to close this PR if you don't think that this is a good idea.

doc/rustc: describe the uefi target platforms
Add a `platform-support` entry to the rustc-docs for the different `*-unknown-uefi` targets. This describes in detail how this platform works, a few basic examples, and how to compile for the platform.
Red Hat is sponsoring my work on this platform, so I am putting myself down as target maintainer. Co-maintainers are more than welcome to join me in the effort. Communication is going on off-list to coordinate the different efforts.
Note that the ultimate goal is to move the UEFI targets to Tier-2 so bootloaders can be more easily supported in commercial products. This documentation is the first step towards that goal, but should be a viable documentation even for the current Tier-3 status of the targets.
I also want to point out that there is an ongoing GSoC-effort to port the rust standard library to UEFI (by Ayush Singh). While this work is not necessarily required to get to Tier-2, we definitely should coordinate the efforts and update the documentation as soon as any such ports are merged.
Note that the targets are already used by multiple commercial and non commercial production systems, including, but not limited to:
* Tianocore-EDK2 (Official UEFI SDK by Intel) comes with rust support
in its staging repository (not part of any release, yet).
(https://github.com/tianocore/edk2-staging/tree)
* Intel's research program "Project Mu" uses the rust UEFI targets to
show possible future replacements for Tianocore-EDK2.
* The Rust OS "Redox" uses the UEFI targets for its bootloader.
(https://www.redox-os.org/)
* The hugely popular in-depth documentation of OS development in Rust
by Philipp Oppermann uses the UEFI targets.

add suggestion when there is a impl of external trait on pointer with wrong coherence rules
Closes https://github.com/rust-lang/rust/issues/99572
This will try to improve the node in the error message by suggesting a general solution because the solution, in this case, is application depended.
I'm not super happy regarding the code quality, but I'm happy to have feedback on it.

A `TokenStream` contains a `Lrc<Vec<(TokenTree, Spacing)>>`. But this is
not quite right. `Spacing` makes sense for `TokenTree::Token`, but does
not make sense for `TokenTree::Delimited`, because a
`TokenTree::Delimited` cannot be joined with another `TokenTree`.
This commit fixes this problem, by adding `Spacing` to `TokenTree::Token`,
changing `TokenStream` to contain a `Lrc<Vec<TokenTree>>`, and removing the
`TreeAndSpacing` typedef.
The commit removes these two impls:
- `impl From<TokenTree> for TokenStream`
- `impl From<TokenTree> for TreeAndSpacing`
These were useful, but also resulted in code with many `.into()` calls
that was hard to read, particularly for anyone not highly familiar with
the relevant types. This commit makes some other changes to compensate:
- `TokenTree::token()` becomes `TokenTree::token_{alone,joint}()`.
- `TokenStream::token_{alone,joint}()` are added.
- `TokenStream::delimited` is added.
This results in things like this:
```rust
TokenTree::token(token::Semi, stmt.span).into()
```
changing to this:
```rust
TokenStream::token_alone(token::Semi, stmt.span)
```
This makes the type of the result, and its spacing, clearer.
These changes also simplifies `Cursor` and `CursorRef`, because they no longer
need to distinguish between `next` and `next_with_spacing`.

Because the default is empty and it's never overridden. This means
`walk_ident` can also be removed, because it does nothing.

Generate correct suggestion with named arguments used positionally
Address issue #99265 by checking each positionally used argument
to see if the argument is named and adding a lint to use the name
instead. This way, when named arguments are used positionally in a
different order than their argument order, the suggested lint is
correct.
For example:
```
println!("{b} {}", a=1, b=2);
```
This will now generate the suggestion:
```
println!("{b} {a}", a=1, b=2);
```
Additionally, this check now also correctly replaces or inserts
only where the positional argument is (or would be if implicit).
Also, width and precision are replaced with their argument names
when they exists.
Since the issues were so closely related, this fix for issue #99265
also fixes issue #99266.

LLVM 15 compatibility fixes
These are LLVM 15 compatibility fixes split out from #99464. There are three changes here:
* Emit elementtype attribtue for ldrex/strex intrinsics. This is requires as part of the opaque pointers migration.
* Make more tests compatible with opaque pointers. These are either new or aren't run on x86.
* Remove a test for `#[rustc_allocator]`. Since #99574 there are more requirement on the function signature. I dropped the test entirely, since we already test the effect of the attribute elsewhere.
* The main change: When a worker thread emits an error, wait for other threads to finish before unwinding the main thread and exiting. Otherwise workers may end up using globals for which destructors have already been run. This was probably never quite correct, but became an active problem with LLVM 15, because it started using global dtors in critical places, as part of ManagedStatic removal.
Fixes #99432 (and probably also #95679).

fix: remove fake no_dead_strip for osx
Closes https://github.com/rust-lang/rust/issues/99788
Link arg `-no_dead_strip` doesn't exist on OSX at all.
The `no_gc_sections` function was never called before export-executable-symols implementation, and `export-executable-symbols` still works, so we just remove it.
