Adds an overload of `_DebuggerSupport.stringForPrintObject` which takes a pointer and mangled typename as arguments. This will be used to improve performance and resilience of `po` in lldb.
The pointer and mangled typename are used to construct an `Any` value, which is then passed into the primary implementation of `stringForPrintObject`.
This allows calling `stringForPrintObject` without having to first construct a context that contains all necessary Swift modules. This will improve speed, and also resilience when modules cannot be loaded for whatever reason.

Instead of using weak definitions of swift_retain_preservemost and swift_release_preservemost, use weak references and explicitly check them for NULL.
Embedded Swift uses weak definitions for its runtime symbols. If swiftCore is able to override the weak definitions of the _preservemost functions, it will also override the Embedded symbols. They are not compatible, so this ends poorly.

Adds logic to insert newlines in various places to try and resolve the
fact that the current expansion produces invalid code in some cases
depending on comment location. Adds some basic tests of the expansion
output.
On Windows, `GUID` is a currency type and (along with its various
typedefs) is used pervasively Windows offers `IsEqualGUID()` and
`UuidHash()` for comparing and hashing them, respectively, but
`IsEqualGUID()` is a macro in C mode and `UuidHash()` only provides a
16-bit hash. We should provide conformance to these protocols in the
WinSDK overlay to provide equivalent functionality in Swift.
This adds the -verify-ignore-unrelated flag. When -verify is used without -verify-ignore-unrelated, diagnostics emitted in buffers other than the main file and those passed with -verify-additional-file (except diagnostics emitted at <unknown>:0) will now result in an error. They were previously ignored. The old behaviour is still available as opt-in using -verify-ignore-unrelated, but by being strict by default it should make it harder to accidentally miss diagnostics.
To avoid unnecessary performance overhead, -verify-additional-file is still required to parse the expected-* directives in files other than the main file.
These are tests that fail in the next commit without this flag. This
does not add -verify-ignore-unrelated to all tests with -verify, only
the ones that would fail without it. This is NFC since this flag is
currently a no-op.
libswiftOSLogTestHelper is built with add_swift_target_library, which is
used for runtime components, and we only support building those for
13.0+. These back-deploy bots are meant to test against the OS's
libraries, since that's what's actually used when back-deploying, but
that's not right for this library.

Cover all va_list family of types just aliased by __builtin_va_list, including __isoc_va_list from wasi-libc. This enables proper C interop for variable argument functions on WASI targets.

This fixes modularization errors that arise when importing a C++ header that contains `#include <guiddef.h>`, which might hijack this header from the WinSDK module where it belongs.
The interior wrapping in Result<T, U> is a little unfortunate, but is
currently necessary because we end up with extra stack allocations
along the error-handling path in a do..catch that aren't there when
using untyped throws. We can simplify the implementation if we can
eliminate the extraneous stack allocation.
Fixes rdar://134973620.
