offset_of: allow (unstably) taking the offset of slice tail fields
Fields of type `[T]` have a statically known offset, so there is no reason to forbid them in `offset_of!`. This PR adds the `offset_of_slice` feature to allow them.
I created a tracking issue: https://github.com/rust-lang/rust/issues/126151.
Add a custom Command wrapper to `run-make-support`
This should make it easier to make sure that we check process exit codes, and it should also make checking of stdout/stderr less verbose and more explicit in run-make tests. I prefer the `run()/run_fail().assert(...)` style to something like `run_fail_assert_exit_code`, because the former is more composable.
Regarding https://github.com/rust-lang/rust/issues/125747, I'm not sure if we really need a custom trait, I think that we can get far enough with just `Deref` on the `Cc/Clang/Rustc/Rustdoc/...` structs. But now that these structs don't even need `command_output` anymore, I think that they are fine-ish as they are with the macro.

Fixes: https://github.com/rust-lang/rust/issues/125617 (because `command_output` is no longer a public method)

add missing Scalar::from_i128
We seem to have `from` methods for all primitive types except `i128`... let's complete the set of methods. (This came up in https://github.com/rust-lang/miri/pull/3622.)
Change how runmake v2 tests are executed
This PR makes execution of v2 runmake tests more sane, by executing each test in a temporary directory by default, rather than running it inside `tests/run-make`. This will have.. a lot of conflicts.
Fixes: https://github.com/rust-lang/rust/issues/126080
Closes https://github.com/rust-lang/rust/issues/125726, because it removes `tmp_dir`, lol.

Port `tests/run-make-fulldeps/hotplug_codegen_backend` to ui-fulldeps
This is the last remaining run-make-fulldeps test, which means I actually had to leave behind a dummy README file to prevent compiletest from complaining about a missing directory.
(Removing the run-make-fulldeps suite entirely is non-trivial, so I intend to do so in a separate PR after this one.)
---
I wasn't sure about adding a new kind of aux build just for this one test, so I also tried to just port this test from Makefile to [rmake](https://github.com/rust-lang/rust/issues/121876) instead.
But I found that I couldn't get rmake to fully work for a run-make-fulldeps test, which convinced me that getting rid of run-make-fulldeps is worthwhile.

Add debugging utils and comments to Fuchsia scripts
This should help when debugging a failure in the Fuchsia build in CI.
I plan to follow up with a PR to the testing section of the dev guide with more details, along with more improvements happening in the Fuchsia repo itself.

mark binding undetermined if target name exist and not obtained
- Fixes#124490
- Fixes#125013
Following up on #124840, I think handling only `target_bindings` is sufficient.

Make html rendered by rustdoc allow searching non-English identifier / alias
Fix alias search result showing `undefined` description.
Inspired by https://github.com/rust-lang/mdBook/issues/2393 .
Not sure if it's worth it adding full-text search functionality to rustdoc rendered html.
std::unix::fs::get_mode implementation for illumos/solaris.
they both support the F_GETFL fctnl flag/O_ACCMODE mask to get the file descriptor access modes.

Improve docs for using custom paths with `--emit`
Recently I found myself concluding that this feature didn't exist (https://github.com/rust-lang/rust/pull/126111#discussion_r1630707215), despite having read the documentation, because it was hidden away in the middle of a paragraph full of other information.
Giving this documentation more space of its own should make it easier to find.
Clean up source root in run-make tests
The name `S` isn't exactly the most descriptive, and we also shouldn't need to pass it when building (actually I think that most of the env. vars that we pass to `cargo` here are probably not really needed).

Revert "Use the HIR instead of mir_keys for determining whether something will have a MIR body."
This reverts commit e5cba17b84.
turns out SMIR still needs it (https://github.com/model-checking/kani/issues/3218). I'll create a full plan and MCP for what I intended this to be a part of. Maybe my plan is nonsense anyway.
