StdlibUnittest is built with `-disable-implicit-concurrency-module-import`
and it uses concurrency feature. Therefore, without explicit import,
StdlibUnittest.swiftmodule doesn't have `IMPORTED_MODULE` entry of
`_Concurrency`. And it results link-failure when static linking because
swift_Concurrency is not linked.

Remove the option that explicitly enables concurrency back-deployment,
and instead always enable its support in the compiler. Remove the use
of the extraneous CMake option as well.
When build-script is given `--back-deploy-concurrency`, also use that
to build other parts of Swift with the back-deployed versions:
* The compiler allows async and actors to be defined with the
back-deployed availability, e.g., the same as `-Xfrontend
-enable-experimental-back-deploy-concurrency`. (The latter will go
away soon)
* The standard library unit testing framework and distributed actors
library are build with the older OS versions.
* The tests use the older OS versions, with some adjustments to make
them agnostic to the back-deployment setting.
The SIL type lowering logic for AutoDiff gets the substituted generic signature
mixed up with the invocation generic signature, so it tries to ask questions
about DependentMemberTypes in a signature with no requirements. This triggers
assertions when the requirement machine is enabled.
Disable the requirement machine until this is fixed.
This fixes verification of emitted swiftinterface files.

Implement a version of projectExistential tailored for LLDB. There are 2
differences when projecting existentials for LLDB:
1 - When it comes to existentials, LLDB stores the address of the error
pointer, which must be dereferenced.
2 - When the existential wraps a class type, LLDB expects the address
returned is the class instance itself and not the address of the
reference.
This patch also adapts the swift reflection test machinery to test
projectExistentialAndUnwrapClass as well. This is done by exposing
the new functionality from swift reflection test. It is tested in
existentials.swift, and ensures that the typeref information is
exactly the same as what is expected from projectExistential,
except the out address.

The support for running concurrency tests individually with filters
invoked the non-concurrent supporting `runOneTest` accidentally. Fix
this to us the `runOneTestAsync` allowing the single async test to be
run in process again. This is needed for ease of debugging (and in the
case of Windows, the only option for debugging).

For various reasons, it can be useful/interesting to create builds of
Swift that minimize dependencies. Let's try to keep that working as long
as we can.
This patch plumbs through the ability to run async code in the standard
library unittests. The async start-point is `runAllTestsAsync` and must
be called from an async context. For now, that means calling through
async-main.
* [stdlib] Deprecate MutableCollection._withUnsafeMutableBufferPointerIfSupported
In Swift 5.0, [SE-0237] introduced the public `MutableCollection.withContiguousMutableStorageIfAvailable` method. It’s time we migrated off the old, underscored variant and deprecated it.
The default `MutableCollection.sort` and `.partition(by:)` implementations are currently calling this hidden method rather than the documented interface, preventing custom Collection implementations from achieving good performance, even if they have contiguous storage.

Compiler:
- Add `Forward` and `Reverse` to `DifferentiabilityKind`.
- Expand `DifferentiabilityMask` in `ExtInfo` to 3 bits so that it now holds all 4 cases of `DifferentiabilityKind`.
- Parse `@differentiable(reverse)` and `@differentiable(_forward)` declaration attributes and type attributes.
- Emit a warning for `@differentiable` without `reverse`.
- Emit an error for `@differentiable(_forward)`.
- Rename `@differentiable(linear)` to `@differentiable(_linear)`.
- Make `@differentiable(reverse)` type lowering go through today's `@differentiable` code path. We will specialize it to reverse-mode in a follow-up patch.
ABI:
- Add `Forward` and `Reverse` to `FunctionMetadataDifferentiabilityKind`.
- Extend `TargetFunctionTypeFlags` by 1 bit to store the highest bit of differentiability kind (linear). Note that there is a 2-bit gap in `DifferentiabilityMask` which is reserved for `AsyncMask` and `ConcurrentMask`; `AsyncMask` is ABI-stable so we cannot change that.
_Differentiation module:
- Replace all occurrences of `@differentiable` with `@differentiable(reverse)`.
- Delete `_transpose(of:)`.

When not building with the standard library with the host compiler and
building the check target for Swift from clean, we would mis-order the
build for the BlocksRuntimeStubs which depends on the just built
compiler. Ensure that CMake knows this dependency.
A CMake refactoring in apple/swift#34859 caused failures in Mac Catalyst configurations which are not tested in open source. This commit corrects these issues.
Fixes rdar://71897958.
BlocksRuntimeStubs is built for the target SDK(s), but it was using one
of the stdlib CMake helpers without setting up the same environment as
the stdlib/ folder is setting.
To avoid problems, like BlocksRuntimeStubs being built with the host
compiler, instead of the just built compiler, and other difficult to
understand problems, create a folder for it in stdlib/private/. This
will allow the usage of the stdlib CMake function in the same environment
that is normally used.
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.
The compiler stubs for testing the OSLog implementation are in need of an update. This change updates the stubs to be consistent with the current OSLog implementation, updates the existing tests, and adds new tests for String and metatype interpolations.

Clean up a few general patterns that are now obviated by canImport
This aligns more generally with the cleanup that the Swift Package
Manager has already done in their automated XCTest-plumbing tool in
apple/swift-package-manager#1826.
Previously, metadata prespecialization for classes only occurred when
all of a specialized generic class's ancestors were themselves generic.
Here, that requirement is lifted so that generic classes with concrete
ancestors are also eligible for prespecialization.
This replaces `LLVM_LIBRARY_VISIBILITY` with `SWIFT_LIBRARY_VISIBILTIY`
througout the runtime. The purpose of this attribution is unclear -
building with `-fvisibility=hidden` would accomplish this. This is an
entirely mechanical change replacing the macro with the Swift namespaced
variant instead.
