Ignore empty RUSTC_WRAPPER in bootstrap
This change ignores the RUSTC_WRAPPER_REAL environment variable if it's
set to the empty string. This matches cargo behaviour and allows users
to easily shadow a globally set RUSTC_WRAPPER (which they might have set
for non-rustc projects).

rustdoc: use stability, instead of features, to decide what to show

Fixes #124635

To decide if internal items should be inlined in a doc page, check if the crate is itself internal, rather than if it has the rustc_private feature flag. The standard library uses internal items, but is not itself internal and should not show internal items on its docs pages.

Rollup merge of #124761 - Urgau:ref-casting_bigger_slice_index, r=jieyouxu
Fix insufficient logic when searching for the underlying allocation

This PR fixes the logic inside the `invalid_reference_casting` lint, when trying to lint on bigger memory layout casts.

More specifically when looking for the "underlying allocation" we were wrongly assuming that when we got `&mut slice[index]` that `slice[index]` was the allocation, but it's not.

Fixes https://github.com/rust-lang/rust/issues/124685

rustc: Some small changes for the wasm32-wasip2 target

This commit has a few changes for the wasm32-wasip2 target. The first two are aimed at improving the compatibility of using `clang` as an external linker driver on this target. The default target to LLVM is updated to match the Rust target and additionally the `-fuse-ld=lld` argument is dropped since that otherwise interferes with clang's own linker detection. The only linker on wasm targets is LLD but on the wasip2 target a wrapper around LLD, `wasm-component-ld`, is used to drive the process and perform steps necessary for componentization.

The final commit changes the output of all objects on the wasip2 target to being PIC by default. This improves compatibilty with shared libaries but notably does not mean that there's a turnkey solution for shared libraries. The hope is that by having the standard libray work both with and without dynamic libraries will make experimentation easier.

Convert instances of `target_os = "macos"` to `target_vendor = "apple"`

https://github.com/rust-lang/rust/pull/124491 migrated towards using `target_vendor = "apple"` more, as there's very little difference between iOS, tvOS, watchOS and visionOS. In that PR, I only did the changes where the standard library already had fixes for iOS, that I could confidently apply to the other targets.

However, there's actually also not that big of a gap between macOS and the aforementioned platforms - so in this PR, I've gone through a few of the instances of `target_os = "macos"` and replaced it with `target_vendor = "apple"` to improve support on those platforms, see the commits for details.

Fuchsia test runner: fixup script

This commit fixes several issues in the fuchsia-test-runner.py script:

1. Migrate from `pm` to `ffx` for package management, as `pm` is now deprecated. Furthermore, the `pm` calls used in this script no longer work at Fuchsia's HEAD. This is the largest change in this commit, and impacts all steps around repository management (creation and registration of the repo, as well as package publishing).

2. Allow for `libtest` to be either statically or dynamically linked. The script assumed it was dynamically linked, but the current Rust behavior at HEAD is to statically link it.

3. Minor cleanup to use `ffx --machine json` rather than string parsing.

4. Minor cleanup to the docs around the script.

b68b92041c Simplify use crate::rustc_foo::bar occurrences.
They can just be written as `use rustc_foo::bar`, which is far more
standard. (I didn't even know that a `crate::` prefix was valid.)

Improve `rustc_parse::Parser`'s debuggability

The main event is the final commit where I add `Parser::debug_lookahead`. Everything else was basically cleaning up things that bugged me (debugging, as it were) until I felt comfortable enough to actually work on it.

The motivation is that it's annoying as hell to try to figure out how the debug infra works in rustc without having basic queries like `debug!(?parser);` come up "empty". However, Parser has a lot of fields that are mostly irrelevant for most debugging, like the entire ParseSess. I think `Parser::debug_lookahead` with a capped lookahead might be fine as a general-purpose Debug impl, but this adapter version was suggested to allow more choice, and admittedly, it's a refined version of what I was already handrolling just to get some insight going.

5e67a3783c compiler: add Parser::debug_lookahead
I tried debugging a parser-related issue but found it annoying to not be
able to easily peek into the Parser's token stream.

but one that is useful for answering basic questions about parser state.

38b2bd782b rustc: Change wasm32-wasip2 to PIC-by-default
This commit changes the new `wasm32-wasip2` target to being PIC by
default rather than the previous non-PIC by default. This change is
intended to make it easier for the standard library to be used in a
shared object in its precompiled form. This comes with a hypothetical
modest slowdown but it's expected that this is quite minor in most use
cases or otherwise wasm compilers and/or optimizing runtimes can elide
the cost.

Do not ICE on `AnonConst`s in `diagnostic_hir_wf_check`

Fixes #122989

Below is the snippet from #122989 that ICEs:
```rust
trait Traitor<const N: N<2> = 1, const N: N<2> = N> {
    fn N(&N) -> N<2> {
        M
    }
}

trait N<const N: Traitor<2> = 12> {}
```

The `AnonConst` that triggers the ICE is the `2` in the param `const N: N<2> = 1`. The currently existing code in `diagnostic_hir_wf_check` deals only with `AnonConst`s that are default values of some param, but  the `2` is not a default value. It is just an `AnonConst` HIR node inside a `TraitRef` HIR node corresponding to `N<2>`. Therefore the existing code cannot handle it and this PR ensures that it does.

rustdoc: dedup search form HTML

This change constructs the search form HTML using JavaScript, instead of plain HTML. It uses a custom element because

- the [parser]'s insert algorithm runs the connected callback synchronously, so we won't get layout jank
- it requires very little HTML, so it's a real win in size

[parser]: https://html.spec.whatwg.org/multipage/parsing.html#create-an-element-for-the-token

This shrinks the standard library by about 60MiB, by my test.

There should be no visible changes. Just use less disk space.
