Remove an outdated line from a test comment
They *used* to not work, however this was fixed in the PR that added the test. I forgot to remove this line or possibly lost its removal while rebasing.

Remove usage of legacy scheme paths on RedoxOS
The `name:/path` path syntax is getting phased out[^1] in favor of `/scheme/name/path`. Also using `null:` is no longer necessary as `/dev/null` is available on Redox OS too.

EUV: fix place of deref pattern's interior's scrutinee
The place previously used here was that of the temporary holding the reference returned by `Deref::deref` or `DerefMut::deref_mut`. However, since the inner pattern of `deref!(inner)` expects the deref-target type itself, this would ICE when that type was inspected (e.g. by the EUV case for slice patterns). This adds a deref projection to fix that.
Since current in-tree consumers of EUV (upvar inference and clippy) don't care about Rvalues, the place could be simplified to `self.cat_rvalue(pat.hir_id, self.pat_ty_adjusted(subpat)?)` to save some cycles. I personally find EUV to be a bit fragile, so I've opted for pedantic correctness. Maybe a `HACK` comment would suffice though?

Visit `PatField` when collecting lint levels
Fixes#138428
Side-note, I vaguely skimmed over the other nodes we could be visiting here and it doesn't *seem* to me that we're missing anything, though I may be mistaken given recent(?) support for attrs in where clauses(??). Can be fixed in a follow-up PR.
fix: remove the check of lld not supporting @response-file
In LLVM v9, lld has supported `@response-file.`
LLVM v9 was released on 2019-09-19.
The check was added back to 2018-03-14 (1.26.0) via 04442af18b.
It has been more than five years, and we ship our own lld regardlessly.
This should be happily removed.

atomic intrinsics: clarify which types are supported and (if applicable) what happens with provenance
The provenance semantics match what Miri implements and what the `AtomicPtr` API expects.
Enable metrics and verbose tests in PR CI
When debugging CI, I relatively often need to examine what tests are executed on PR CI, and what bootstrap steps does it execute. However, we currently disable both verbose tests and bootstrap metrics on PR CI for some reason.
I'm not actually sure why though, as the PR that (probably) introduced this behavior (https://github.com/rust-lang/rust/pull/51367) didn't explain why.

use `expect` instead of `allow`
This is more useful than `allow` as compiler will force us to remove rules that are no longer valid (we already got a few of them in this change).
Add `src/tools/x` to the main workspace
The original reason to exclude it was so it could run before submodules
were initialized. However, those have all been converted to subtrees
now, so the entire workspace is always ready to go.
I've also alphabetized the workspace members, as it was an untidy mess. 🧹
Improve HashMap docs for const and static initializers
Closes#137566.
I clarified the HashMap usage in const and static initializers.
I also added examples of how to construct such HashMaps wrapped in LazyLock.
Sync Fuchsia target spec with clang Fuchsia driver
This updates the Fuchsia target spec with the [Clang Fuchsia driver], which picks up a few changes:
* Adds `-z start-stop-visibility=hidden` and `-z rel` to the pre link arguments.
* Adds `--execute-only` and `--fix-cortex-a53-843419` for `aarch64-unknown-fuchsia`.
* Enables the equivalent cpu features for `x86-64-v2` for `x86_64-unknown-fuchsia`, which is our minimum supported x86_64 platform according to [RFC-0073].

Reword incorrect documentation about SocketAddr having varying layout
This has no longer been the case since these types were moved to `core`. The note on portability remains, but it is reworded to not imply that the size varies by target.
Allow more top-down inlining for single-BB callees
This means that things like `<usize as Step>::forward_unchecked` and `<PartialOrd for f32>::le` will inline even if
we've already done a bunch of inlining to find the calls to them.
Fixes#138136
~~Draft as it's built atop #138135, which adds a mir-opt test that's a nice demonstration of this. To see just this change, look at <48f63e3be5>~~ Rebased to be just the inlining change, as the other existing tests show it great.
Don't `alloca` just to look at a discriminant
Today we're making LLVM do a bunch of extra work when you match on trivial stuff like `Option<bool>` or `ControlFlow<u8>`.
This PR changes that so that simple types like `Option<u32>` or `Result<(), Box<Error>>` can stay as `OperandValue::ScalarPair` and we can still read the discriminant from them, rather than needing to write them into memory to have a `PlaceValue` just to get the discriminant out.

Fix RISC-V VxWorks LLVM target triples
The targets `riscv32-wrs-vxworks` and `riscv64-wrs-vxworks` uses the plain `$ARCH` LLVM triple, which LLVM normalizes to `$ARCH-unknown-unknown`, we should use `$ARCH-unknown-linux-gnu$ABI` which is consistent with the the other VxWorks targets.
Motivation: To make it easier to verify that [`cc-rs`' conversion from `rustc` to Clang/LLVM triples](https://github.com/rust-lang/cc-rs/issues/1431) is correct.
Alternative: Pass `$ARCH-unknown-none` in the other VxWorks LLVM triples, I don't know anything about VxWorks, so am unsure which is the most correct option.

minor interpreter cleanups
- remove the `eval_inline_asm` hook that `@saethlin` added; the usage never materialized and he agreed with removing it
- I tried merging `init_alloc_extra` and `adjust_global_allocation` and it didn't work; leave a comment as to why. Also, make the allocation code path a bit more clear by renaming `init_alloc_extra` to `init_local_allocation`.

Add an opt-out in pretty printing for RTN rendering
Today, we render RPITIT types like `impl Sized { T::method(..) }` when RTN is enabled. This is very useful for diagnostics, since it's often not clear what the `impl Sized` type means by itself, and it makes it clear that that's an RPITIT that can be bounded using RTN syntax. See #115624.
However, since we don't distinguish types that are rendered for the purposes of printing messages vs suggestions, this representation leaks into suggestions and turns into code that can't be parsed. This PR adds a new `with_types_for_suggestion! {}` and `with_types_for_signature! {}` options to the pretty printing architecture to make it clear that we're rendering a type for code suggestions.
This can be applied later as we find that we need it.
Add a .bss-like scheme for encoded const allocs
This check if all bytes are zero feel like it should be too slow, and instead we should have a flag that we track, but that seems hard. Let's see how this perfs first.
Also we can probably stash the "it's all zero actually" flag inside one of the other struct members that's already not using an entire byte. This optimization doesn't fire all that often, so it's possible that by sticking it in the varint length field, this PR actually makes rmeta size worse.
The name:/path path syntax is getting phased out in favor of
/scheme/name/path. Also using null: is no longer necessary as /dev/null
is available on Redox OS too.
