The Apple SDKs have been providing the Darwin overlay since macOS 10.14.4, iOS 12.2, et al. More recently the SDK version has diverged from the Swift version making them incompatible. Stop building the overlay from Swift. Once the SDK overlays aren't being built, the clang overlays need to be built in testing.
%target-swift-emit-pcm doesn't use the sdk, but %target-swift-frontend does, which will cause them to have a mismatch with "builtin headers belong to system modules, and _Builtin_ modules are ignored for cstdlib headers" aka LANGOPT(BuiltinHeadersInSystemModules) aka -fbuiltin-headers-in-system-modules.

Bump the deployment target from macOS 10.13-aligned versions to macOS
13.0-aligned versions. This allows us to stop linking CoreFoundation
in the swift runtime, which was previously required for availability
checking. It also lets us align the deployment target on x86_64 with
arm64, which was 11.0. Finally, it is a prerequisite to being able to
build swift using the macOS 15 beta SDKs.
- Add simple support for the AVR architecture, as a supported conditional compilation value, and added to the default llvm targets to build.
(Later PRs will fix support for 16-bit pointers, which is broken in places, and any fixes needed to get the standard library to build.)
(Note: AVR as a target is expected to always be compiled with -enable-experimental-feature Embedded.)
Currently those are hardcoded to `-g`, but in some Apple internal
configurations we would like to change them.
There are other part of the build system that hardcode `-g`
(e.g. in `SwiftCompilerSources` and `AddSwiftStdlib.cmake`),
but we are not interested in those at the moment -- we will address those
in the future if need be.

Fix some indentation issues.
Change `build-script-impl` to make `build-linux-static` a positive argument.
Fix documentation for `--linux-archs` and `--linux-static-archs` (the options
are comma separated for `build-script`, but semicolon separated for
`build-script-impl`).
Set the default for `linux-static-archs` to `x86_64, aarch64` so that we
install the expected content in the toolchain.
Add missing default for `test_linux_static`.
Make sure to pass down `--skip-build-linux` and `--build-linux-static`.
Factor out config file generation and call it from the install step in `llvm.py`
as well as from the build step.

Declare a new `LINUX_STATIC` SDK and configure it.
Add options to set the build architectures for the `LINUX` and
`LINUX_STATIC` SDKs, similar to what we have for Darwin, because
we'll be cross-compiling.
Also add an option to point the build system at the sources for
the musl C library, which we're using for `LINUX_STATIC`.

This change introduces a new compilation target platform to the Swift compiler - visionOS.
- Changes to the compiler build infrastrucuture to support building compiler-adjacent artifacts and test suites for the new target.
- Addition of the new platform kind definition.
- Support for the new platform in language constructs such as compile-time availability annotations or runtime OS version queries.
- Utilities to read out Darwin platform SDK info containing platform mapping data.
- Utilities to support re-mapping availability annotations from iOS to visionOS (e.g. 'updateIntroducedPlatformForFallback', 'updateDeprecatedPlatformForFallback', 'updateObsoletedPlatformForFallback').
- Additional tests exercising platform-specific availability handling and availability re-mapping fallback code-path.
- Changes to existing test suite to accomodate the new platform.
Now that the compilation model of noncopyable types is enabled everywhere,
and one can enable the feature for specific modules, we no longer need a
separate build-script/CMake option to enable it globally. Remove it all.
With this build-script has a flag --enable-experimental-nonescpable-types=1
to enable this feature in stdlib.
Also we can now add // REQUIRES: nonescapable_types to tests which run only when
the compiler is built with this feature turned on.
This patch adds a new product, WasmKit, which is a Wasm runtime that is
going to be used to run executable tests targeting Wasm. Note that the
product is not shipped as a part of the toolchain, but is used only for
testing purposes.
