Poison sentinel value recognized by LLDB as a former reference to a

This is not ABI per-se but does stay in-sync with LLDB. If it becomes
out-of-sync, then users won't see a friendly diagnostic when

4f24d895fc [stdlib] Use Clang type macros on OpenBSD.
Per the code comment, stdint.h is provided by clang and therefore
conflicts with Glibc; additionally, clang defines some particular
type macros for making the appropriate `typedef`s.

OpenBSD uses clang-10, so we can also use these types on this platform.
This also addresses a test case that has gone awry.

6b16657922 Explode on uncaught error thrown in main
This patch has two desirable effects for the price of one.
 1. An uncaught error thrown from main will now explode
 2. Move us off of using runAsyncAndBlock

The issue with runAsyncAndBlock is that it blocks the main thread
outright. UI and the main actor need to run on the main thread or bad
things happen, so blocking the main thread results in a bad day for
them.

Instead, we're using CFRunLoopRun to run the core-foundation run loop on
the main thread, or, dispatch_main if CFRunLoopRun isn't available.
The issue with just using dispatch_main is that it doesn't actually
guarantee that it will run the tasks on the main thread either, just
that it clears the main queue. We don't want to require everything that
uses concurrency to have to include CoreFoundation either, but dispatch
is already required, which supplies dispatch_main, which just empties
out the main queue.

4cf189f0ae shims: add a workaround for sqrtf on Windows x86
When building for Windows x86, we have a few conspiring issues to
contend with.  `__builtin_sqrtf` is treated by clang as a `__builtin_`
prefixed libm call.  On windows, there is no libm, with the role being
taken up by ucrt.  However, on 32-bit x86 targets, ucrt does not provide
an implementation of `sqrtf` instead defining it inline as a wrapper
which widens the argument to a double precision and invokes `sqrt`, the
result of which is narrowed to the result.  This function is locally
defined and expected to be inlined and no out-of-line definition is
provided by ucrt that can be referenced.

Adjusting the shims to use the intrinsics would be the next option
(thanks @stephentyrone!) which would work.  However, when building the
standard library, we need to combine the system headers which results in
the use of the MSVCRT headers for `xmmintrin.h` rather than clang.  As a
result, we cannot directly use the intrinsics.

Opt to instead open-code the intrinsic path by using the compiler
builtin for sqrt.  This both yields the optimal implementation and
avoids providing an additional entry point in the runtime.  It also has
code size benefits.

A special thanks to @stephentyrone for all the discussion and help with
this!

de2dbe57ed [AutoDiff] Bump-pointer allocate pullback structs in loops. (#34886)
In derivatives of loops, no longer allocate boxes for indirect case payloads. Instead, use a custom pullback context in the runtime which contains a bump-pointer allocator.

When a function contains a differentiated loop, the closure context is a `Builtin.NativeObject`, which contains a `swift::AutoDiffLinearMapContext` and a tail-allocated top-level linear map struct (which represents the linear map struct that was previously directly partial-applied into the pullback). In branching trace enums, the payloads of previously indirect cases will be allocated by `swift::AutoDiffLinearMapContext::allocate` and stored as a `Builtin.RawPointer`.

4e39e59a8a Add a field reflection function that constructs keypaths. (#34815)
While the existing _forEachField in ReflectionMirror.swift
already gives the offsets and types for each field, this isn't
enough information to construct a keypath for that field in
order to modify it.

For reference, this should be sufficent to implement the features
described here: (https://forums.swift.org/t/storedpropertyiterable/19218/62)
purely at runtime without any derived conformances for many types.

Note: Since there isn't enough reflection information for
`.mutatingGetSet` fields, this means that we're not able to support
reflecting certain types of fields (functions, nonfinal class fields,
etc). Whether this is an error or not is controlled by the `.ignoreUnknown`
option.

5d30503894 When parsing floating-point from String, underflow to 0, overflow to infinity (#34339)
Previously, overflow and underflow both caused this to return `nil`, which causes several problems:
* It does not distinguish between a large but valid input and a malformed input.  `Float("3.402824e+38")` is perfectly well-formed but returns nil
* It differs from how the compiler handles literals.  As a result, `Float(3.402824e+38)` is very different from `Float("3.402824e+38")`
* It's inconsistent with Foundation Scanner()
* It's inconsistent with other programming languages

This is exactly the same as #25313

8ac4362754 Implement a simple library for task cancellation and status management.
There are things about this that I'm far from sold on.  In
particular, I'm concerned that in order to implement escalation
correctly, we're going to have to add a status record for the
fact that the task is being executed, which means we're going
to have to potentially wait to acquire the status lock; overall,
that means making an extra runtime function call and doing some
atomics whenever we resume or suspend a task, which is an
uncomfortable amount of overhead.

The testing here is pretty grossly inadequate, but I wanted to
lay down the groundwork here.

7eff49c1b6 [cxx-interop] [nfc] Remove swift namespace from SwiftShims in C++ mode. (#32715)
Most SwiftShims were put in the swift namespace in C++ mode which broke certain things when importing them in a swift file in C++ mode. This was OK when they were only imported as part of the swift runtime but, now they are used in C++ mode both in the swift runtime and when C++ interop is enabled.

This broke when C++ interop was enabled because the `Swift` module contains references to symbols in the SwiftShims headers which are built without C++ interop enabled (no "swift" namespace). But, when C++ interop is enabled, the SwiftShims headers would put everything in the swift namespace meaning the symbols couldn't be found in the global namespace. Then, the compiler would error when trying to deserialize the Swift module.

Move the ObjC class name stability check logic to the Swift runtime, exposing it as a new SPI called _swift_isObjCTypeNameSerializable.

Update the reporting logic. The ObjC names of generic classes are considered stable now, but private classes and classes defined in function bodies or other anonymous contexts are unstable by design.

On the overlay side, rewrite the check’s implementation in Swift and considerably simplify it.

This assert is _probably_ wrong in LLVM because the local extern
reference isn't being handled properly and needs to be addressed there.
We could move the declaration to global scope, but that is not ideal
because it makes the pointer declaration visible to Swift.

OpenBSD needs to implement _swift_stdlib_getEnviron regardless, so
let's do so.

a7415423e6 runtime: add and switch to SWIFT_FALLTHROUGH (NFC)
This duplicates and switches the uses of `LLVM_FALLTHROUGH` to a local
macro for the same annotation.

e0b0d20cd8 runtime: add and switch to SWIFT_NORETURN (NFC)

LLVMSupport.

This further trims dependencies to LLVMSupport by introducing the
equivalent `SWIFT_USED` macro.

f465ec0345 runtime: add and switch to SWIFT_NOINLINE (NFC)
This switches the `LLVM_ATTRIBUTE_NOINLINE` to a local copy which is
namespaced in Swift.

9731704cc7 runtime: replace LLVM_LIBRARY_VISIBILITY with SWIFT_LIBRARY_VISIBILITY (NFC)
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.
