The SDK overlays have been provided in the Apple SDKs for many years, and the interface and implementation has diverged in more recent years such that trying to build the Swift version no longer works. Remove all of the dead code.

... that would import that as a result of importing Darwin from the SDK.
Amend my previous change to Differentiation and Distributed in this
sense.

Mostly this just means adding `Musl` as a module dependency of various
things and making sure that we build things for `swift_static` even
if `SWIFT_BUILD_STATIC_STDLIB` isn't enabled.
There's also a slight difference in the declaration of `memcmp()`;
musl's declaration is more like the one we have on Darwin.

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.
Build SwiftReflectionTest only if swift-reflection-test is available
because it depends on the tool and the tool is not available when no
dynamic stdlib is built
This replaces swiftMSVCRT with swiftCRT. The big difference here is
that the `visualc` module is no longer imported nor exported. The
`visualc` module remains in use for a singular test wrt availability,
but this should effectively remove the need for the `visualc` module.
The difference between the MSVCRT and ucrt module was not well
understood by most. MSVCRT provided ucrt AND visualc, combining pieces
of the old MSVCRT and the newer ucrt. The ucrt module is what you
really wanted most of the time, however, would need to use MSVCRT for
the convenience aliases for type-generic math and the deprecated math
constants.
Unfortunately, we cannot shadow the `ucrt` module and create a Swift SDK
overlay for ucrt as that seems to result in circular dependencies when
processing the `_Concurrency` module.
Although this makes using the C library easier for most people, it has a
more important subtle change: it cleaves the dependency on visualc.
This means that this enables use of Swift without Visual Studio for the
singular purpose of providing 3 header files. Additionally, it removes
the need for the installation of 2 of the 4 support files. This greatly
simplifies the deployment process on Windows.
Ensure that the swift-reflection-test binary is built for Windows by
default. This is preventing tests from executing on Windows. There are
dependencies which were already specified for Linux even, the tool just
was disabled due to an invalid check.
There are situations where you want to build against a libc that is out
of tree or that is not the system libc (Or for cross build scenarios).
This is a change for passing the -sdk and include paths for things like
this.
The key thing here is that all of the underlying code is exactly the same. I
purposely did not debride anything. This is to ensure that I am not touching too
much and increasing the probability of weird errors from occurring. Thus the
exact same code should be executed... just the routing changed.
These changes caused a number of issues:
1. No debug info is emitted when a release-debug info compiler is built.
2. OS X deployment target specification is broken.
3. Swift options were broken without any attempt any recreating that
functionality. The specific option in question is --force-optimized-typechecker.
Such refactorings should be done in a fashion that does not break existing
users and use cases.

This patch splits add_swift_library into two functions one which handles
the simple case of adding a library that is part of the compiler being
built and the second handling the more complicated case of "target"
libraries, which may need to build for one or more targets.
The new add_swift_library is built using llvm_add_library, which re-uses
LLVM's CMake modules. In adapting to use LLVM's modules some of
add_swift_library's named parameters have been removed and
LINK_LIBRARIES has changed to LINK_LIBS, and LLVM_LINK_COMPONENTS
changed to LINK_COMPONENTS.
This patch also cleans up libswiftBasic's handling of UUID library and
headers, and how it interfaces with gyb sources.
add_swift_library also no longer has the FILE_DEPENDS parameter, which
doesn't matter because llvm_add_library's DEPENDS parameter has the same
behavior.
When building on a macOS host, and when `SWIFT_INCLUDE_TESTS` is specified,
the `swiftSwiftReflectionTest` target is added to all platforms.
However, this target has a dependency upon Foundation, which is not
available on non-Apple platforms.
Use `add_swift_library`'s `TARGET_SDKS` parameter and other gating
logic to ensure the target is only added for platforms that actually
have Darwin available.
As a first step to allowing the build script to build *only*
static library versions of the stdlib, change `add_swift_library`
such that callers must pass in `SHARED`, `STATIC`, or `OBJECT_LIBRARY`.
Ideally, only these flags would be used to determine whether to
build shared, static, or object libraries, but that is not currently
the case -- `add_swift_library` also checks whether the library
`IS_STDLIB` before performing certain additional actions. This will be
cleaned up in a future commit.
Eventually this tool will test solely with the C API, so wire up
the dependencies now. This also fixes an annoying dependency issue
when building some testing configurations.

It appears a little redundant but this follows the convention of the
other private stdlib library targets, where "SwiftReflectionTest" is
the module name, so it should be included in the target name.
This is a small helper library to communicate information back to
swift-reflection-test from a test swift executable. Each swift test
file under test/Reflection should link this library to get the main
test hook to send responses back to the test tool.
