Fix HIR printing of parameters
HIR pretty printing does the wrong thing for anonymous parameters, and there is no test coverage for it. This PR remedies both of those things.

Refactor is_snake_case.
I wondered what the definition of this actually was, and found the original hard to read. I believe this change preserves the original behavior, but is hopefully clearer.
Improve post-merge workflow
Contains various fixes for the post-merge workflow implemented in https://github.com/rust-lang/rust/pull/138013, which were suggested on Zulip. This PR changes the grouping of test diffs and ignores doctests, as they are too noisy.
I'll post an example output (before/after this PR) in comments below.

Pass `CI_JOB_DOC_URL` to Docker
Fix-up for https://github.com/rust-lang/rust/pull/136911. I always forget to pass new environment variables to Docker images.. 🤦♂️

Remove `RUN_CHECK_WITH_PARALLEL_QUERIES`
After https://github.com/rust-lang/rust/pull/132282, I'm pretty sure that this is simply useless? It just runs check with an empty config, lol.

remove must_use from <*const T>::expose_provenance
`<*mut T>::expose_provenance` does not have this attribute, and in fact the function is documented to have a side-effect, so there are perfectly legitimate use-cases where the return value would be ignored.
Provide helpful diagnostics for shebang lookalikes
When `[` is not found after a `#!`, a note will be added to the exisiting error
```
error: expected `[`, found `/`
--> src/main.rs:2:3
|
2 | #!/usr/bin/env -S cargo +nightly -Zscript
| ^ expected `[`
|
= note: the token sequence `#!` here looks like the start of a shebang interpreter directive but it is not
= help: if you meant this to be a shebang interpreter directive, move it to the very start of the file
```

uefi: helpers: Add DevicePathNode abstractions
- UEFI device path is a series of nodes layed out in a contiguous memory region. So it makes sense to use Iterator abstraction for modeling DevicePaths
- This PR has been split off from #135368 for easier review. The allow dead_code will be removed in #135368

Remove an outdated line from a test comment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.
Fixes#137503
