rustdoc: remove no-op mobile CSS `.content { margin-left: 0 }`
This rule was added to override non-zero left margin on `.content`, which was removed in 135281ed1525db15edd8ebd092aa10aa40df2386 and the margin-left was put on the docblock.
Point out span where we could introduce higher-ranked lifetime
Somewhat addresses #105422, but not really. We don't have that much useful information here since we're still in resolution :^(
Maybe this suggestion isn't worth it. If the reviewer has an idea how we can get a more succinct binder information for a structured suggestion, it would be appreciated.
Fix process-panic-after-fork.rs to pass on newer versions of Android.
The test process-panic-after-fork.rs was checking that abort() resulted in SIGSEGV on Android. This non-standard behavior was fixed back in 2013, so let's fix the test to also accept the standard behavior on Android.
Migrate `codegen_ssa` to diagnostics structs - [Part 3]
Completes migrating `codegen_ssa` module except 2 outstanding errors that depend on other crates:
1. [`rustc_middle::mir::interpret::InterpError`](b6097f2e1b/compiler/rustc_middle/src/mir/interpret/error.rs (L475)): I saw `rustc_middle` is unassigned, I am open to take this work.
2. `codegen_llvm`'s use of `fn span_invalid_monomorphization_error`, which I started to replace in the [last commit](9a31b3cdda) of this PR, but would like to know the team's preference on how we should keep replacing the other macros:
2.1. Update macros to expect a `Diagnostic`
2.2. Remove macros and expand the code on each use.
See [some examples of the different options in this experimental commit](64aee83e80)

Migrating rustc_infer to session diagnostics (part 3)
``@rustbot`` label +A-translation
r? rust-lang/diagnostics
cc https://github.com/rust-lang/rust/issues/100717
Seems like a part of static_impl_trait.rs emits suggestions in a loop, and note.rs needs to have two instances of the same subdiagnostic, so these will need to wait until we have eager translation/list support.
Other than that, there is only error_reporting/mod.rs left to migrate.
Add help diag. for `const = Enum` missing braces around `Enum`
Previously it was not clear why this errored or if it was even supported, as there was no diagnostic that suggested wrapping it in braces.
Thus, add a simple diagnostic that suggests wrapping enum variants in braces.

rustdoc: remove no-op CSS `.rustdoc.source .sidebar { width: 0 }`
This CSS was added in dc2c9723343c985740be09919236a6e96c4e4433, before 6a5f8b1aef1417d7dc85b5d0a229d2db1930eb7c when the sidebars were merged.
Now that they are merged, the source sidebar is being pushed off-screen anyway, so giving it zero width doesn't do much.

Handle non-existent upstream master branches in `x fmt`
People who do have a remote for `rust-lang/rust` but don't have the master branch checked out there used to get this error when running `x fmt`:
> fatal: ambiguous argument 'rust/master': unknown revision or path not in the working tree.
> Use '--' to separate paths from revisions, like this:
> 'git <command> [<revision>...] -- [<file>...]'
> rust/master
Which is not exactly helpful.
Now, we fall back to `origin/master` (hoping that at least that remote exists) for that case. If there is still some error, we just fall back to `x fmt .` and print a warning.

Add default and latest stable edition to --edition in rustc (attempt 2)
Fixes#106041
No longer leaks string like my first attempt PR, #106094 - uses LazyLock to construct a `&'static str`
It will now output the default edition and latest stable edition in the help message for the `--edition` flag.
Going to request the same reviewer as the first attempt for continuity - r? `@Nilstrieb`
Fix rustdoc source code rendering for `#[path = "../path/to/mod.rs"]` links
Fixes#103517
While generating the location for modules source HTML to be saved at, a `..` path component appeared to be translated to `/up/`.
Additionally, while generating the navigation sidebar, `..` path components were ignored. This means that (as in the issue above), a *real* directory structure of:
```
sys/
unix/
mod.rs <-- contains #![path = "../unix/mod.rs]
cmath.rs
```
was rendered as:
```
sys/
unix/
mod.rs
unix/
cmath.rs <-- links to sys/unix/unix/cmath.rs.html, 404
```
While the *files* were stored as
```
sys/
unix/
mod.rs.html
up/
unix/
cmath.rs.html
```
Improve include macro documentation
As outlined in #106118, the `include!` macro is a SEO problem when it comes to the Rust documentation. Beginners may see it as a replacement to `include` syntax in other languages. I feel like this documentation should quite explicitly link to the modules' documentation.
The primary goal of this PR is to address that issue by adding a warning to the documentation. While I was here, I also added some other parts. This included a `Uses` section and some (intra doc) links to other relevant topics.
I hope this can help beginners to Rust more quickly understand some multi-file project intricacies.

refactor: clean up `errors.rs` and `error_codes_check.rs`
`errors.rs` is basically unused now, `error_codes_check.rs` is useful but not well commented, etc. It also doesn't check certain things which are certainly not correct. For example, `E0505` has a UI test in `src/test/ui/error-codes/` but that test actually outputs `E0504`?! Other issues like these exist. I've implemented these with "warnings" which are a bit rough around the edges but should be removed eventually.
