Remove dead code

Missing }

./x.py fmt

Remove duplicate check

Recursively remove all usage of help_on_error
The oldest occurence is from 9e224c2,
which is from the pre-1.0 days. In the years since then, std::sys still
hasn't been exported, and the last attempt was met with strong criticism:
rust-lang#97151

Thus, removing the "yet" part makes a lot of sense.

Use Box::new() instead of box syntax in library tests

The tests inside `library/*` have no reason to use `box` syntax as they have 0 performance relevance. Therefore, we can safely remove them (instead of having to use alternatives like the one in rust-lang#97293).
Remove "sys isn't exported yet" phrase

The oldest occurence is from 9e224c2,
which is from the pre-1.0 days. In the years since then, std::sys still
hasn't been exported, and the last attempt was met with strong criticism:

Ensure source file present when calculating max line number

Resubmission of rust-lang#89268, fixes rust-lang#71363
The behavior difference of `simulate-remapped-rust-src-base` is not something we should take into account here, so limiting targets to run the test makes sense, I think.

Re-add help_on_error for download-ci-llvm

Closes rust-lang#97503

- Re-added `help_on_error` for `download_component()` and the downstream functions
- Removed dead code in `bootstrap.py`

Thanks `@jyn514` for the helpful tips!

(first contribution here, please let me know if I missed anything out!)

Note pattern mismatch coming from `for` loop desugaring

Fixes rust-lang#97163
Reword safety comments in core/hash/sip.rs

In https://rust-lang.zulipchat.com/#narrow/stream/136281-t-lang.2Fwg-unsafe-code-guidelines/topic/Is.20there.20any.20way.20to.20soundly.20do.20a.20masked.20out-of-bounds.20read.3F/near/284329248 it came up that this is using an atypical (and somewhat vague) phrasing of the safety requirement, so this slightly rewords it.
