The main point of this change is to make sure that a shared function always has a body: both, in the optimizer pipeline and in the swiftmodule file.
This is important because the compiler always needs to emit code for a shared function. Shared functions cannot be referenced from outside the module.
In several corner cases we missed to maintain this invariant which resulted in unresolved-symbol linker errors.
As side-effect of this change we can drop the shared_external SIL linkage and the IsSerializable flag, which simplifies the serialization and linkage concept.
Swiftmodule loading was previously restricted by compiler tag only for
resilient modules. This left room for resilient modules with a corrupted
control block to pass as non-resilient modules.
Apply the same check for non-resilient modules (so all modules) when
read from a tagged compiler.

[Distributed] Adjust interface of `swift_distributed_execute_target`
Since this is a special function, `calleeContext` doesn't point to
a direct parent but instead both parent context (uninitialized)
and resume function are passed as last arguments which means that
`callContext` has to act as an intermediate context in call to accessor.

[Distributed] Implement func metadata and executeDistributedTarget
dont expose new entrypoints
able to get all the way to calling _execute
This adds tracking of the vtable holes due to a failure to deserialize
vtable entries. This allows for the user to be able to identify what
member failed to be deserialied and can aid in understanding why an
`open` class may not be subclassed.
Future improvements here would allow tracing the XRefPath which failed
to be deserialied. However, this still provides an improvement over the
existing experience where there is no available information on why the
class cannot be inherited from.
The "regular" CMO is done with the option `-cross-module-optimization`. It's good for performance but can increase code size.
Now, which this change CMO is also done if the option is not given, but in a very conservative way. Only very small functions are serialized and not additional type metadata is kept alive.

The `Qr` mangling is used to refer to the opaque type within the
declaration that produces the opaque type. When there are multiple
opaque types, e.g., due to structural or named opaque result types, it
does not specify which of the opaque type parameters it refers to.
Introduce a new mangling `QR INDEX` for opaque type parameters after
the first, retaining the `Qr` mangling for the first opaque type
parameter. This way, existing (non-structural) uses of opaque result
types retain the same manglings, but uses of structural or named
opaque result types (new features) will have distinct manglings.
Note that this mangling within a declaration is only used for the
declaration itself, and not for references to the opaque type of the
declaration, so there is no impact on the runtime demangler.
Introduce a new instruction `dealloc_stack_ref ` and remove the `stack` flag from `dealloc_ref`.
The `dealloc_ref [stack]` was confusing, because all it does is to mark the deallocation of the stack space for a stack promoted object.
Enable the Serialization/restrict-swiftmodule-to-revision on Windows.
This test was unnecessarily disabled on Windows due to the use of
environment variables which can be accommodated by using the `env`
command.

We noticed some Swift clients rely on the serialized search paths in the module to
find dependencies and droping these paths altogether can lead to build failures like
rdar://85840921.
This change teaches the serialization to obfuscate the search paths and the deserialization
to recover them. This allows clients to keep accessing these paths without exposing
them when shipping the module to other users.
We've recently added the -experimental-hermetic-seal-at-link compiler flag,
which turns on aggressive dead-stripping optimizations and assumes that library
code can be optimized against client code because all users of the library
code/types are present at link/LTO time. This means that any module that's
built with -experimental-hermetic-seal-at-link requires all clients of this
module to also use -experimental-hermetic-seal-at-link. This PR enforces that
by storing a bit in the serialized module, and checking the bit when importing
modules.
Required for UnsafeRawPointer.withMemoryReboud(to:).
%out_token = rebind_memory %0 : $Builtin.RawPointer to %in_token
%0 must be of $Builtin.RawPointer type
%in_token represents a cached set of bound types from a prior memory state.
%out_token is an opaque $Builtin.Word representing the previously bound
types for this memory region.
This instruction's semantics are identical to ``bind_memory``, except
that the types to which memory will be bound, and the extent of the
memory region is unknown at compile time. Instead, the bound-types are
represented by a token that was produced by a prior memory binding
operation. ``%in_token`` must be the result of bind_memory or

%token is an opaque $Builtin.Word representing the previously bound types

Replace the dynamic initialization of trivial globals with statically initialized globals, even in -Onone.
This is required to be able to use global variables in performance-annotated functions.
Also, it's a small performance improvement for -Onone.
