Trivial conflict caused by the line above the
`IGM.constructInitialFnAttributes` change in `lib/IRGen/GenDecl.cpp`
having an extra argument passed in rebranch (due to the new LLVM API).
This patch gets everything to the point of building the library, but it
doesn't run yet since I have missing symbols.
Unlike previous compatibility libraries and the concurrency
compatibility library, I'm organizing the headers a bit more. This is
because we're merging the two libraries into one. They share some common
header names, and while I could rename them for namespacing purposes,
it's easier to just use a directory structure for this.
The `include/Runtime` and corresponding `Runtime/` directories are for
backdeployed changes to the stdlib itself.
The `include/Concurrency` and corresponding `Concurrency/` directories
are for backdeployed changes to the concurrency runtimes.
Adds frontend option -enable-stack-protector to enable emission of a
stack protector.
Disabled by default.
When enabled enables LLVM's strong stack protection mode.

I am separating the concern of weakly linking symbols that are introduced at the deployment target from the concern of type checking this new type of potential unavailability.

Put pointers to class_ro_t referenced from generic class patterns in a section __swift_rodatas such that they are discoverable by the linker.
The linker can then make the method lists contained in the class_ro_t relative like it can for objective c class metadata from non-generic swift classes.

This was already enabled as part of `-enable-implicit-dynamic` but this
new flag allows turning on opaque type erasure all by itself whether or
not `dynamic` is added explicitly.

Introduce the `-enable-upcoming-feature X` command-line argument to
allow one to opt into features that will be enabled in an upcoming language
mode. Stage in several features this way (`ConciseMagicFile`,
`ForwardTrailingClosures`, `BareSlashRegexLiterals`).
* Lookup for custom derivatives in non-primary source files after typecheck is finished for the primary source.
This registers all custom derivatives before autodiff transformations and makes them available to them.
Fully resolves#55170
Prebuilt modules are only available for certain toolchain and SDK combinations. Therefore,
building modules from interface, even for the stdlib, is expected to happen.

Defined SWIFT_STDLIB_TASK_TO_THREAD_MODEL_CONCURRENCY to describe
whether the standard library will use the task-to-thread model for
concurrency. It is true only for freestanding non-Darwin stdlibs.
When it is true, SWIFT_CONCURRENCY_TASK_TO_THREAD_MODEL is defined
during stdlib compilation of both Swift and C++ sources.
Added an option to LangOptions to specify which concurrency model is
used, either standard or task-to-thread. When
SWIFT_STDLIB_TASK_TO_THREAD_MODEL_CONCURRENCY is true, the model is
specified to be task-to-thread.
