A couple tests were using `BOOTSTRAP_CARGO` with `-Zbuild-std`, but that
stage0 cargo might not always be in sync with in-tree changes. In
particular, those tests started failing on the beta branch because the
older cargo couldn't find the library `Cargo.lock`, and then couldn't
build the latest version of `compiler_builtins` that had nightly changes.
Add test for S_OBJNAME & update test for LF_BUILDINFO cl and cmd
Update the unit test for checking cl and cmd in LF_BUILDINFO. With llvm-pdbutil we can now more specifically check if the string appears at the right location instead of just checking whether the string exists at all.

Fix default/minimum deployment target for Aarch64 simulator targets
The minimum that `rustc` encoded did not match [the version in Clang](https://github.com/llvm/llvm-project/blob/llvmorg-18.1.8/llvm/lib/TargetParser/Triple.cpp#L1900-L1932), and that meant that that when linking, Clang ended up bumping the version. See https://github.com/rust-lang/rust/issues/129432 for more motivation behind this change.
Specifically, this PR sets the correct deployment target of the following targets:
- `aarch64-apple-ios-sim` from 10.0 to 14.0
- `aarch64-apple-tvos-sim` from 10.0 to 14.0
- `aarch64-apple-watchos-sim` from 5.0 to 7.0
- `aarch64-apple-ios-macabi` from 13.1 to 14.0
I have chosen not to document the `-sim` changes in the platform support docs, as it is fundamentally uninteresting; the normal targets (e.g. `aarch64-apple-ios`) still have the same deployment target, and that's what developers should actually target.

Pass deployment target when linking with CC on Apple targets
This PR effectively implements what's also being considered in the `cc` crate [here](https://github.com/rust-lang/cc-rs/issues/1030#issuecomment-2051020649), that is:
- When linking macOS targets with CC, pass the `-mmacosx-version-min=.` option to specify the desired deployment target. Also, no longer pass `-m32`/`-m64`, these are redundant since we already pass `-arch`.
- When linking with CC on iOS, tvOS, watchOS and visionOS, only pass `-target` (we assume for these targets that CC forwards to Clang).
This is required to get the linker to emit the correct `LC_BUILD_VERSION` of the final binary. See https://github.com/rust-lang/rust/issues/129432 for more motivation behind this change.

r? ````````@Kobzol````````
I've opened other PRs for this one to work and they've landed already. I cherry-picked your commit, and added the last remaining pieces we needed I think.
When linking macOS targets with cc, pass the `-mmacosx-version-min=.`
option to specify the desired deployment target. Also, no longer pass
`-m32`/`-m64`, these are redundant since we already pass `-arch`.
When linking with cc on other Apple targets, always pass `-target`.
(We assume for these targets that cc => clang).
The minimum that `rustc` encoded did not match the version in Clang, and
that meant that that when linking, we ended up bumping the version.
Specifically, this sets the correct deployment target of the following
simulator and Mac Catalyst targets:
- `aarch64-apple-ios-sim` from 10.0 to 14.0
- `aarch64-apple-tvos-sim` from 10.0 to 14.0
- `aarch64-apple-watchos-sim` from 5.0 to 7.0
- `aarch64-apple-ios-macabi` from 13.1 to 14.0
I have chosen to not document the simulator target versions in the
platform support docs, as it is fundamentally uninteresting; the normal
targets (e.g. `aarch64-apple-ios`, `aarch64-apple-tvos`) still have the
same deployment target as before, and that's what developers should
actually target.
* All new functionality is under unstable options
* Adds `--merge=shared|none|finalize` flags

`--merge=finalize` to write cross-crate info files
* update tests/run-make/rustdoc-default-output/rmake.rs golden

Add missing `needs-llvm-components` directives for run-make tests that need target-specific codegen
Without suitable `needs-llvm-components` directives, some run-make tests exercising target-specific codegen can fail if the LLVM used is built without the necessary components. Currently, the list is:
```
tests\run-make\print-target-list
tests\run-make\print-to-output
tests\run-make\print-cfg
tests\run-make\target-without-atomic-cas
```
This PR also skips tidy checks for revisions and `needs-llvm-components` for run-make tests since revisions are not supported.
Fixes#129390.
Fixes#127895.

More work on `zstd` compression
r? ``@Kobzol`` as we've discussed this.
This is a draft to show the current approach of supporting zstd in compiletest, and making the tests using it unconditional.
Knowing whether llvm/lld was built with `LLVM_ENABLE_ZSTD` is quite hard, so there are two strategies. There are details in the code, and we can discuss this approach. Until we know the config used to build CI artifacts, it seems our options are somewhat limited in any case.
zlib compression seems always enabled, so we only check this in its dedicated test, allowing the test to ignore errors due to zstd not being supported.
The zstd test is made unconditional in what it tests, by relying on `needs-llvm-zstd` to be ignored when `llvm.libzstd` isn't enabled in `config.toml`.

Migrate `x86_64-fortanix-unknown-sgx-lvi` `run-make` test to rmake
Part of #121876 and the associated [Google Summer of Code project](https://blog.rust-lang.org/2024/05/01/gsoc-2024-selected-projects.html).
The final Makefile! Every Makefile test is now claimed.
This is difficult to test due to the uncommon architecture it is specific to. I don't think it is in the CI (I didn't find it in `jobs.yml`, but if there is a way to test it, please do.
Locally, on Linux, it compiles and panics at the `llvm_filecheck` part (if I replace the `x86_64-fortanix-unknown-sgx` with `x86_64-unknown-linux-gnu`, of course), which is expected.
For this reason, the Makefile and associated script have been kept, but with a leading underscore.
Allow rust staticlib to work with MSVC's /WHOLEARCHIVE
This fixes#129020 by renaming the `__NULL_IMPORT_DESCRIPTOR` to prevent conflicts.

Trying to get rid of this Python script looks tempting, because it's currently
the only Python script in the whole `run-make` suite that we actually run.
But getting rid of it would require pulling in a Rust crate to parse XML
instead, and that's probably not worth the extra hassle for a relatively-minor
test.
Disable `dump-ice-to-disk` for i686-mingw (again)
To avoid blocking full CI or `i686-mingw` try jobs (failed in https://github.com/rust-lang/rust/pull/127679#issuecomment-2295184771).
At least we now have some context for why the assertion failed.
Anyone with r+ can approve this.
Port `run-make/libtest-json/validate_json.py` to Rust
This is a trivial Python script that simply tries to parse each line of stdin (i.e. the test process output) as JSON, to verify that the overall output is JSON Lines.
We can perform the same check directly in `rmake.rs` using `serde_json`.
r? ````@jieyouxu````
Re-enable `dump-ice-to-disk` for Windows
This test was previously flakey on `i686-mingw` (reason unknown), but since some modifications (quarantining each ICE test in separate tmp dirs, adding/removing `RUSTC_ICE` env vars as suitable to prevent any kind of environmental influence), I could no longer make it fail on `i686-mingw`.
I tried running this test (without the `ignore-windows` of course) a bunch of times via `i686-mingw` try jobs and it refused to fail (see #128958). I was also never able to reproduce the failure locally.
In any case, if this turns out to be still flakey on `i686-mingw`, we can revert the removal of `ignore-windows` but this time we'll have way more context for why the test failed.
Running the `i686-mingw` alongside some Windows jobs for basic santiy check. But the try jobs succeeding is insufficient to guarantee reproducibility.

Detect multiple crate versions on method not found
When a type comes indirectly from one crate version but the imported trait comes from a separate crate version, the called method won't be found. We now show additional context:
```
error[E0599]: no method named `foo` found for struct `dep_2_reexport::Type` in the current scope
--> multiple-dep-versions.rs:8:10
|
8 | Type.foo();
| ^^^ method not found in `Type`
|
note: there are multiple different versions of crate `dependency` in the dependency graph
--> multiple-dep-versions.rs:4:32
|
4 | use dependency::{do_something, Trait};
| ^^^^^ `dependency` imported here doesn't correspond to the right crate version
|

Fix#128569, fix#110926, fix#109161, fix#81659, fix#51458, fix#32611. Follow up to #124944.
This is a trivial Python script that simply tries to parse each line of stdin
(i.e. the test process output) as JSON, to verify that the overall output is
JSON Lines.
We can perform the same check directly in `rmake.rs` using `serde_json`.
Port the `sysroot-crates-are-unstable` Python script to rmake
New version of #126231, and a follow-up to #129071.
One major difference is that the new version no longer tries to report *all* accidentally-stable crates, because the `run_make_support` helpers tend to halt the test as soon as something goes wrong. That's unfortunate, but I think it won't matter much in practice, and preserving the old behaviour doesn't seem worth the extra effort.

Part of #110479 (Python purge), with this being one of the non-trivial Python scripts that actually seems feasible and worthwhile to remove.
This is *not* part of #121876 (Makefile purge), because the underlying test is already using rmake; this PR just modifies the existing rmake recipe to do all the work itself instead of delegating to Python. So there's no particular urgency here.

Coalesce `dep-info`, `dep-info-spaces` and `dep-info-doesnt-run-much` `run-make` tests into `dep-info` rmake.rs
Part of #121876 and the associated [Google Summer of Code project](https://blog.rust-lang.org/2024/05/01/gsoc-2024-selected-projects.html).
This is one of the most ancient tests in the `run-make` directory and its Makefile does some unexpected things, like creating and deleting a `done` directory over and over, sleeping at certain times (this is the [commit](0d9fd8e2a1) that added the `sleep`).
I tried to preserve the intent of the test, which is smoke-testing that `dep-info` works.

Add possibility to generate rustdoc JSON output to stdout
