Revert "Introduce lowering_arena to avoid creating AST nodes on the fly"
This reverts commit d9a1faaa9c (#101499).
This was originally part of #101345 which has now been closed as a different approach is taken now.

print argument name in arg mismatch if possible
A bit more contextual than just `/* value */`, at least when the argument is named something related to its context.
The UI test cases are... not super convincing, but also they're minimized tests.
Remove the `..` from the body, only a few invocations used it and it's
inconsistent with rust syntax.
Use `;` instead of `,` between consts. As the Rust syntax gods inteded.
This removes the `custom` format functionality as its only user was
trivially migrated to using a normal format.
If a new use case for a custom formatting impl pops up, you can add it
back.
Fix `x setup -h -v` should work
r? `@jyn514`
I have to convert profile to path and back in order to remove special-casing in bootstrap. I also check for `dry_run` so that `config.toml` and/ or `.git/hooks/pre-push` will not be created if `--dry-run` is specified.
Please help me see if this is ok, thanks alot!
Run `x test tidy` sooner in mingw-check
It takes less time to run than the other tests and is more likely to fail. `expand-yaml-anchors` is still run first to make sure the CI files are internally consistent.
Note that changing to `--stage 0` doesn't actually do anything since bootstrap tools are always built with the bootstrap compiler, this just makes it less confusing.

Migrate rustc_mir_build diagnostics
Rebases https://github.com/rust-lang/rust/pull/100854
~~The remaining issue is how to better resolve 72bea68af4~~
~~The diagnostic macros seems to generate a broken diagnostic, and I couldn't figure out how to manually format the fluent message, so I hardcoded the format string for now. I'd like pointers to a better fix for this.~~
Also, I'm not 100% sure I didn't mess up a rebase somewhere 🙂

fs: Fix#50619 (again) and add a regression test
Bug #50619 was fixed by adding an end_of_stream flag in #50630.
Unfortunately, that fix only applied to the readdir_r() path. When I
switched Linux to use readdir() in #92778, I inadvertently reintroduced
the bug on that platform. Other platforms that had always used
readdir() were presumably never fixed.
This patch enables end_of_stream for all platforms, and adds a
Linux-specific regression test that should hopefully prevent the bug
from being reintroduced again.
std::fmt: Use args directly in example code
The lint "clippy::uninlined_format_args" recommends inline variables in format strings. Fix two places in the docs that do not do this. I noticed this because I copy/pasted one example in to my project, then noticed this lint error. This fixes:
```
error: variables can be used directly in the `format!` string
--> src/main.rs:30:22
|
30 | let string = format!("{:.*}", decimals, magnitude);
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
error: variables can be used directly in the `format!` string
--> src/main.rs:39:2
|
39 | write!(&mut io::stdout(), "{}", args).unwrap();
```

Support call and drop terminators in custom mir
The only caveat with this change is that cleanup blocks are not supported. I would like to add them, but it's not quite clear to me what the best way to do that is, so I'll have to think about it some more.

rustdoc: clean up margin CSS for scraped examples
* This stops applying a margin to the additional example links. Because these links are `display: inline`, it doesn't actually do anything.
* This switches from using a margin-bottom with a special exception for the examples themselves, plus an additional margin on the hide button, to instead using just margin-top on the examples, with an exception for the first one.
No user-visible changes should result from this.
Allow blocking `Command::output`
### Problem
Currently, `Command::output` is internally implemented using `Command::spawn`. This is problematic because some targets (like UEFI) do not actually support multitasking and thus block while the program is executing. This coupling does not make much sense as `Command::output` is supposed to block until the execution is complete anyway and thus does not need to rely on a non-blocking `Child` or any other intermediate.
### Solution
This PR moves the implementation of `Command::output` to `std::sys`. This means targets can choose to implement only `Command::output` without having to implement `Command::spawn`.
### Additional Information
This was originally conceived when working on https://github.com/rust-lang/rust/pull/100316. Currently, the only target I know about that will benefit from this change is UEFI.
This PR can also be used to implement more efficient `Command::output` since the intermediate `Process` is not actually needed anymore, but that is outside the scope of this PR.
Since this is not a public API change, I'm not sure if an RFC is needed or not.
