sys: use `process::abort()` instead of `arch::wasm32::unreachable()`

Rationale:

  - `abort()` lowers to `wasm32::unreachable()` anyway.
  - `abort()` isn't `unsafe`.
  - `abort()` matches the comment better.
  - `abort()` avoids confusion by future readers (e.g. https://github.com/rust-lang/rust/pull/81527): the naming of wasm's `unreachable` instruction is a bit unfortunate because it is not related to the `unreachable()` intrinsic (intended to trigger UB).

Codegen is likely to be different since `unreachable()` is `inline` while `abort()` is `cold`. Since it doesn't look like we are expecting here to trigger this case, the latter seems better anyway.

`lint_node_id`, which is something that actually exists in the AST (an
`async fn` or async closure).

Improve handling of spans around macro result parse errors

Fixes #81543

After we expand a macro, we try to parse the resulting tokens as a AST
node. This commit makes several improvements to how we handle spans when
an error occurs:

* Only ovewrite the original `Span` if it's a dummy span. This preserves
  a more-specific span if one is available.
* Use `self.prev_token` instead of `self.token` when emitting an error
  message after encountering EOF, since an EOF token always has a dummy
  span
* Make `SourceMap::next_point` leave dummy spans unused. A dummy span
  does not have a logical 'next point', since it's a zero-length span.
  Re-using the span span preserves its 'dummy-ness' for other checks

Implement <https://github.com/rust-lang/rfcs/pull/2714>

### tl;dr

This PR adds a `extend_from_within` method to `Vec` which allows copying elements from a range to the end:

```rust
#![feature(vec_extend_from_within)]

let mut vec = vec![0, 1, 2, 3, 4];

vec.extend_from_within(2..);
assert_eq!(vec, [0, 1, 2, 3, 4, 2, 3, 4]);

vec.extend_from_within(..2);
assert_eq!(vec, [0, 1, 2, 3, 4, 2, 3, 4, 0, 1]);

vec.extend_from_within(4..8);
assert_eq!(vec, [0, 1, 2, 3, 4, 2, 3, 4, 0, 1, 4, 2, 3, 4]);
```

### Implementation notes

Originally I've copied `@Shnatsel's` [implementation](https://github.com/WanzenBug/rle-decode-helper/blob/690742a0de158d391b7bde1a0c71cccfdad33ab3/src/lib.rs#L74) with some minor changes to support other ranges:
```rust
pub fn append_from_within<R>(&mut self, src: R)
where
    T: Copy,
    R: RangeBounds<usize>,
{
    let len = self.len();
    let Range { start, end } = src.assert_len(len);;

    let count = end - start;
    self.reserve(count);
    unsafe {
        // This is safe because `reserve()` above succeeded,
        // so `self.len() + count` did not overflow usize
        ptr::copy_nonoverlapping(
            self.get_unchecked(src.start),
            self.as_mut_ptr().add(len),
            count,
        );
        self.set_len(len + count);
    }
}
```

But then I've realized that this duplicates most of the code from (private) `Vec::append_elements`, so I've used it instead.

Then I've applied `@KodrAus` suggestions from https://github.com/rust-lang/rust/pull/79015#issuecomment-727200852.

Avoid building LLVM just for llvm-dwp

When the LLVM backend is disabled, the llvm-project submodule is not checked out by default. This breaks the bootstrap test for cg_clif. As cg_clif doesn't support split debuginfo anyway llvm-dwp is not necessary. Other backends would likely not want to build LLVM just for llvm-dwp either.

The wheel is going over the search input and the search tab is going under the search results text. The bug was fixed by simply switching to "mobile mode" at a bigger width:

Previously, only the end of pass RSS was indicated. This could easily
lead one to believe that the change in RSS from one pass to the next was
attributable to the second pass, when in fact it occurred between the
end of the first pass and the start of the second.
