Enable `unreachable_pub` lint in core
This PR enables the [`unreachable_pub`](https://doc.rust-lang.org/rustc/lints/listing/allowed-by-default.html#unreachable-pub) as warn in `core`, `rtstartup` and `panic_unwind`.
The motivation is similar to the compiler [MCP: Enable deny(unreachable_pub) on `rustc_*` crates](https://github.com/rust-lang/compiler-team/issues/773#issue-2467219005) :
> "Where is this thing used?" is a question I ask all the time when reading unfamiliar code. Because of this, I generally find it annoying when things are marked with a more permissive visibility than necessary. "This thing marked pub, which other crates is it used in? Oh, it's not used in any other crates."
Another motivation is to help to lint by utilizing it in-tree and seeing it's limitation in more complex scenarios.
The diff was mostly generated with `./x.py fix --stage 1 library/core/ -- --broken-code`, as well as manual edits for code in macros, generated code and other targets.

Recognise new IPv6 documentation range from IETF RFC 9637
This PR adds the `3fff::/20` range defined by [IETF RFC 9637](https://datatracker.ietf.org/doc/rfc9637/) to those ranges which `Ipv6Addr::is_documentation` recognises as a documentation IP.

Partial progress on #132735: Replace extern "rust-intrinsic" with #[rustc_intrinsic] across the codebase
Part of #132735: Replace `extern "rust-intrinsic"` with `#[rustc_intrinsic]` macro
- Updated all instances of `extern "rust-intrinsic"` to use the `#[rustc_intrinsic]` macro.
- Skipped `.md` files and test files to avoid unnecessary changes.

Respect --sysroot for rustc -vV and -Cpasses=list
This is necessary when the specified codegen backend is in a custom sysroot.

Reexport likely/unlikely in std::hint
Since `likely`/`unlikely` should be working now, we could reexport them in `std::hint`. I'm not sure if this is already approved or if it requires approval

When LLVM's location discriminator value limit is exceeded, emit locations with dummy spans instead of dropping them entirely
Dropping them fails `-Zverify-llvm-ir`.
Fixes #135332.

Correct counting to four in cell module docs
It could also be argued that `OnceCell<T>` and `LazyCell<T>` don't really provide safe interior mutability in different ways. But it's a vague enough claim that I'm not sure it's worth being pedantic about.

rustc_resolve: use structured fields in traces
I think this crate was written before `tracing` was adopted, and was manually writing fields into trace logs instead of using structured fields.
I kept function names in the trace messages even though I added `#[instrument]` invocations so that the events will be in named spans, wasn't sure if spans are always printed.

Do not include GCC source code in source tarballs
The licensing story is unclear, it makes the archive much larger, and we should not need it for building anything in the tarballs (yet).
```
Before:
121s building the archive
1.3 GiB gzipped size
5.7 GiB extracted size
402519 extracted files
After:
64s building the archive
961 MiB gzipped size
4.5 GiB extracted size
257719 extracfed files
```

doc: Point to methods on `Command` as alternatives to `set/remove_var`
Make these methods more discoverable, as configuring a child process is a common reason for manipulating the environment.

Add Profile Override for Non-Git Sources
## PR description
- Fixes #135358
This PR introduces the following updates to
1. `bootstrap.py`:
- If the `profile` is `None` and the source is non-git, the `profile` is automatically overridden to `"dist"`.
- Ensures that options like `download-ci-llvm` and `download-rustc` are not used with non-git sources. An exception is raised if these options are present in the configuration when the source is non-git.
2. `bootstrap_test.py`
- Added unit tests to verify both the profile override mechanism and the assertion for restricted options.
These tests ensure the correct behavior for non-git sources and the handling of `if-unchanged` options.

proc-macro-srv: make usage of RTLD_DEEPBIND portable
|
|
minor: Sync from downstream
|
|
the constant is wrong on some platforms (e.g., on mips64el it's 0x10, and 0x8
is RTLD_NOLOAD which makes all this functionality broken), the libc crate takes
care of those differences for us.
fallback to not setting the flag in non-glibc environments - some of them might
have support for it using a different value that we don't know about, and some
of them lack it entirely.
