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:

./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.
• 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.

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).

Cargo

• [Introduced a new CARGO_MANIFEST_PATH environment variable, similar to CARGO_MANIFEST_DIR but pointing directly to the manifest file.] (rust-lang/cargo#14404)
• [Added package.autolib to the manifest, allowing [lib] auto-discovery to be disabled.] (rust-lang/cargo#14591)
• [Declare support level for each crate in Cargo's Charter / crate docs.] (rust-lang/cargo#14600)
• [Declare new Intentional Artifacts as 'small' changes.] (rust-lang/cargo#14599)

Rustdoc

• [The sidebar / hamburger menu table of contents now includes the # headers from the main item's doc comment] (rust-lang/rust#120736). This is similar to a third-party feature provided by the rustdoc-search-enhancements browser extension.

Compatibility Notes

• [Warn against function pointers using unsupported ABI strings.] (rust-lang/rust#128784)

• [Check well-formedness of the source type's signature in fn pointer casts.] (rust-lang/rust#129021) This partly closes a soundness hole that comes when casting a function item to function pointer

• [Use equality instead of subtyping when resolving type dependent paths.] (rust-lang/rust#129073)

• Linking on macOS now correctly includes Rust's default deployment target. Due to a linker bug, you might have to pass MACOSX_DEPLOYMENT_TARGET or fix your #[link] attributes to point to the correct frameworks. See <rust-lang/rust#129369>.

• [Rust will now correctly raise an error for repr(Rust) written on non-struct/enum/union items, since it previous did not have any effect.] (rust-lang/rust#129422)

• The future incompatibility lint deprecated_cfg_attr_crate_type_name [has been made into a hard error] (rust-lang/rust#129670). It was used to deny usage of #![crate_type] and #![crate_name] attributes in #![cfg_attr], which required a hack in the compiler to be able to change the used crate type and crate name after cfg expansion. Users can use --crate-type instead of #![cfg_attr(..., crate_type = "...")] and --crate-name instead of #![cfg_attr(..., crate_name = "...")] when running rustc/cargo rustc on the command line. Use of those two attributes outside of #![cfg_attr] continue to be fully supported.

• Until now, paths into the sysroot were always prefixed with /rustc/$hash in diagnostics, codegen, backtrace, e.g.

  thread 'main' panicked at 'hello world', map-panic.rs:2:50
  stack backtrace:
     0: std::panicking::begin_panic
               at /rustc/a55dd71d5fb0ec5a6a3a9e8c27b2127ba491ce52/library/std/src/panicking.rs:616:12

  [RFC 3127 said] (https://rust-lang.github.io/rfcs/3127-trim-paths.html#changing-handling-of-sysroot-path-in-rustc)

  We want to change this behaviour such that, when rust-src source files can be discovered, the virtual path is discarded and therefore the local path will be embedded, unless there is a --remap-path-prefix that causes this local path to be remapped in the usual way.

  #129687 implements this behaviour, when rust-src is present at compile time, rustc replaces /rustc/$hash with a real path into the local rust-src component with best effort. To sanitize this, users must explicitly supply --remap-path-prefix=<path to rust-src>=foo or not have the rust-src component installed.

• The allow-by-default missing_docs lint used to disable itself when invoked through rustc --test/cargo test, resulting in #[expect(missing_docs)] emitting false positives due to the expectation being wrongly unfulfilled. This behavior [has now been removed] (rust-lang/rust#130025), which allows #[expect(missing_docs)] to be fulfilled in all scenarios, but will also report new missing_docs diagnostics for publicly reachable #[cfg(test)] items, [integration test] (https://doc.rust-lang.org/cargo/reference/cargo-targets.html#integration-tests) crate-level documentation, and publicly reachable items in integration tests.

• [The armv8r-none-eabihf target now uses the Armv8-R required set of floating-point features.] (rust-lang/rust#130295)

• [Fix a soundness bug where rustc wouldn't detect unconstrained higher-ranked lifetimes in a dyn Trait's associated types that occur due to supertraits.] (rust-lang/rust#130367)

• [Update the minimum external LLVM version to 18.] (rust-lang/rust#130487)

• [Remove aarch64-fuchsia and x86_64-fuchsia target aliases in favor of aarch64-unknown-fuchsia and x86_64-unknown-fuchsia respectively.] (rust-lang/rust#130657)

• [The ABI-level exception class of a Rust panic is now encoded with native-endian bytes, so it is legible in hex dumps.] (rust-lang/rust#130897)

• [Visual Studio 2013 is no longer supported for MSVC targets.] (rust-lang/rust#131070)

• [The sysroot no longer contains the std dynamic library in its top-level lib/ dir.] (rust-lang/rust#131188)

Cargo

• [Introduced a new CARGO_MANIFEST_PATH environment variable, similar to CARGO_MANIFEST_DIR but pointing directly to the manifest file.] (rust-lang/cargo#14404)
• [Added package.autolib to the manifest, allowing [lib] auto-discovery to be disabled.] (rust-lang/cargo#14591)
• [Declare support level for each crate in Cargo's Charter / crate docs.] (rust-lang/cargo#14600)
• [Declare new Intentional Artifacts as 'small' changes.] (rust-lang/cargo#14599)

Rustdoc

• [The sidebar / hamburger menu table of contents now includes the # headers from the main item's doc comment] (rust-lang/rust#120736). This is similar to a third-party feature provided by the rustdoc-search-enhancements browser extension.

Compatibility Notes

• [Warn against function pointers using unsupported ABI strings.] (rust-lang/rust#128784)

• [Check well-formedness of the source type's signature in fn pointer casts.] (rust-lang/rust#129021) This partly closes a soundness hole that comes when casting a function item to function pointer

• [Use equality instead of subtyping when resolving type dependent paths.] (rust-lang/rust#129073)

• Linking on macOS now correctly includes Rust's default deployment target. Due to a linker bug, you might have to pass MACOSX_DEPLOYMENT_TARGET or fix your #[link] attributes to point to the correct frameworks. See <rust-lang/rust#129369>.

• [Rust will now correctly raise an error for repr(Rust) written on non-struct/enum/union items, since it previous did not have any effect.] (rust-lang/rust#129422)

• The future incompatibility lint deprecated_cfg_attr_crate_type_name [has been made into a hard error] (rust-lang/rust#129670). It was used to deny usage of #![crate_type] and #![crate_name] attributes in #![cfg_attr], which required a hack in the compiler to be able to change the used crate type and crate name after cfg expansion. Users can use --crate-type instead of #![cfg_attr(..., crate_type = "...")] and --crate-name instead of #![cfg_attr(..., crate_name = "...")] when running rustc/cargo rustc on the command line. Use of those two attributes outside of #![cfg_attr] continue to be fully supported.

• Until now, paths into the sysroot were always prefixed with /rustc/$hash in diagnostics, codegen, backtrace, e.g.

  thread 'main' panicked at 'hello world', map-panic.rs:2:50
  stack backtrace:
     0: std::panicking::begin_panic
               at /rustc/a55dd71d5fb0ec5a6a3a9e8c27b2127ba491ce52/library/std/src/panicking.rs:616:12
     1: map_panic::main::{{closure}}
               at ./map-panic.rs:2:50
     2: core::option::Option<T>::map
               at /rustc/a55dd71d5fb0ec5a6a3a9e8c27b2127ba491ce52/library/core/src/option.rs:929:29
     3: map_panic::main
               at ./map-panic.rs:2:30
     4: core::ops::function::FnOnce::call_once
               at /rustc/a55dd71d5fb0ec5a6a3a9e8c27b2127ba491ce52/library/core/src/ops/function.rs:248:5
  note: Some details are omitted, run with `RUST_BACKTRACE=full` for a verbose backtrace.

  [RFC 3127 said] (https://rust-lang.github.io/rfcs/3127-trim-paths.html#changing-handling-of-sysroot-path-in-rustc)

  We want to change this behaviour such that, when rust-src source files can be discovered, the virtual path is discarded and therefore the local path will be embedded, unless there is a --remap-path-prefix that causes this local path to be remapped in the usual way.

  #129687 implements this behaviour, when rust-src is present at compile time, rustc replaces /rustc/$hash with a real path into the local rust-src component with best effort. To sanitize this, users must explicitly supply --remap-path-prefix=<path to rust-src>=foo or not have the rust-src component installed.

• The allow-by-default missing_docs lint used to disable itself when invoked through rustc --test/cargo test, resulting in #[expect(missing_docs)] emitting false positives due to the expectation being wrongly unfulfilled. This behavior [has now been removed] (rust-lang/rust#130025), which allows #[expect(missing_docs)] to be fulfilled in all scenarios, but will also report new missing_docs diagnostics for publicly reachable #[cfg(test)] items, [integration test] (https://doc.rust-lang.org/cargo/reference/cargo-targets.html#integration-tests) crate-level documentation, and publicly reachable items in integration tests.

• [The armv8r-none-eabihf target now uses the Armv8-R required set of floating-point features.] (rust-lang/rust#130295)

• [Fix a soundness bug where rustc wouldn't detect unconstrained higher-ranked lifetimes in a dyn Trait's associated types that occur due to supertraits.] (rust-lang/rust#130367)

• [Update the minimum external LLVM version to 18.] (rust-lang/rust#130487)

• [Remove aarch64-fuchsia and x86_64-fuchsia target aliases in favor of aarch64-unknown-fuchsia and x86_64-unknown-fuchsia respectively.] (rust-lang/rust#130657)

• [The ABI-level exception class of a Rust panic is now encoded with native-endian bytes, so it is legible in hex dumps.] (rust-lang/rust#130897)

• [Visual Studio 2013 is no longer supported for MSVC targets.] (rust-lang/rust#131070)

• [The sysroot no longer contains the std dynamic library in its top-level lib/ dir.] (rust-lang/rust#131188)
