As recommended by Clang developers in llvm/llvm-project#88271 (comment), we already specify --target, and that should be enough.

Related: #1029, the -mxros-version-min/-mvisionos-version-min option does not exist.

sounds good to me, IIRC specifying version-min might be related to errors in other projects using cc, maybe even rustc bootstrap, which failed to compile llvm.

Yeah ditching it seems like a fine option. Only thought is maybe compatibility with old (whatever matches 10.12) XCode versions but that might not be a real issue since there is no reason to build iOS (and derivative) apps with anything except the last N-2 XCode releases for app store reasons.

Would the idea be to remove use of -m{}os-version-min and -arch everywhere except macOS?

Maybe platform_version, it seems to support visionos.

     -platform_version platform min_version sdk_version
             This is set to indicate the platform, oldest supported version of that platform that output is to be used on, and the SDK that the output was
             built against.  platform is a numeric value as defined in <mach-o/loader.h>, or it may be one of the following strings:
             • macos
             • ios
             • tvos
             • watchos
             • bridgeos
             • visionos
             • xros
             • mac-catalyst
             • ios-simulator
             • tvos-simulator
             • watchos-simulator
             • visionos-simulator
             • xros-simulator
             • driverkit
             Specifying a newer min or SDK version enables the linker to assume features of that OS or SDK in the output file. The format of min_version
             and sdk_version is a version number such as 10.13 or 10.14

Test codegen when setting deployment target

Test our codegen in different scenarios when setting the deployment target. There are many places here where this is still incorrect, these will be fixed in rust-lang#129342, rust-lang#129367 and rust-lang#129369. See rust-lang#129432 for the bigger picture.

Tested locally using:
```console
./x test tests/run-make/apple-deployment-target --target="aarch64-apple-darwin,aarch64-apple-ios,aarch64-apple-ios-macabi,aarch64-apple-ios-sim,aarch64-apple-tvos,aarch64-apple-tvos-sim,aarch64-apple-visionos,aarch64-apple-visionos-sim,aarch64-apple-watchos,aarch64-apple-watchos-sim,arm64_32-apple-watchos,armv7s-apple-ios,i386-apple-ios,x86_64-apple-darwin,x86_64-apple-ios,x86_64-apple-ios-macabi,x86_64-apple-tvos,x86_64-apple-watchos-sim,x86_64h-apple-darwin"
```

The only Apple targets that aren't tested by the above command are:
- `arm64e-apple-darwin`, failed to build, see rust-lang/cc-rs#1205.
- `armv7k-apple-watchos`, failed to link, see rust-lang#130071.
- `arm64e-apple-ios`, failed to link, see rust-lang#130085.
- `i686-apple-darwin`, requires a bit of setup and an older machine, see [the docs](https://doc.rust-lang.org/nightly/rustc/platform-support/i686-apple-darwin.html).
- `i386-apple-ios` requires you to set `IPHONEOS_DEPLOYMENT_TARGET=10.0` for the test helpers to work, will be fixed by rust-lang/cc-rs#1030.

But all of this is as it was before this PR.

Fixes rust-lang#47825, since we now have a test that compiles a `dylib` for `aarch64-apple-ios`.

Split out from rust-lang#129342, see that for a little bit of the review that this has gone through already.

Pass deployment target when linking with CC on Apple targets

This PR effectively implements what's also being considered in the `cc` crate [here](rust-lang/cc-rs#1030 (comment)), 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 rust-lang#129432 for more motivation behind this change.
