Only the root archetype is a OpaqueTypeArchetypeType; the nested types are
NestedArchetypeType. Use the correct predicate here.
Also remove a dead check in tuple lowering; the isa<OpaqueTypeArchetypeType>()
check is dominated by isTypeParameterOrOpaqueArchetype() which is always
true if isa<OpaqueTypeArchetypeType>() is true anyway.

the enclosing context if the property wrapper is declared in a closure that
does not capture any generic parameters.
In this case, the enclosing closure won't have a generic signature, nor any
substitutions to forward when calling the property wrapper generator, which
previously caused an assertion failure when emitting the call because there
were no substitutions to use.
- If any of the `-g<kind>` flag is given -- except `-gnone`, debug
info will be printed into every generated SIL files.
- The `-gsil` is deprecated in favor of `-sil-based-debuginfo`. The
SILDebugInfoGenerator Pass now generates intermediate SIL file with
name "<output file>.sil_dbg_<n>.sil". Other functionalities of that
Pass remain the same.
Don't allow an owned call argument to be considered a valid BorrowingOperand.
More generally, make sure there is a perfect equivalence between valid
BorrowingOperand and the corresponding OperandOwnership kind.
Rather than using group task options constructed from the Swift parts
of the _Concurrency library and passed through `createAsyncTask`'s
options, introduce a separate builtin that always takes a group. Move
the responsibility for creating the options structure into IRGen, so
we don't need to expose the TaskGroupTaskOptionRecord type in Swift.
Introduce a builtin `createAsyncTask` that maps to `swift_task_create`,
and use that for the non-group task creation operations based on the
task-creation flags. `swift_task_create` and the thin function version
`swift_task_create_f` go through the dynamically-replaceable
`swift_task_create_common`, where all of the task creation logic is
present.
While here, move copying of task locals and the initial scheduling of
the task into `swift_task_create_common`, enabling by separate flags.

A place to define invariants on OperandOwnership that passes can rely
on for convenience.
Starting with a simple invariant the OperandOwnership::Borrow is a
valid BorrowingOperand.
SILGen this builtin to a mandatory hop_to_executor with an actor type
operand.

Task.detached {
Builtin.hopToActor(MainActor.shared)
await suspend()

This is just a shortcut for @_semantics("optremark") to make it easier for
people to remember how to enable assembly vision remarks.
Now one can just type:
```
@_assemblyVision
func foo() {
...
}
```
and get all normal opt-remarks + assembly vision remarks.
With the macro SWIFT_FUNCTION_PASS a new libswift function pass can be defined in Passes.def.
The SWIFT_FUNCTION_PASS_WITH_LEGACY is similar, but it allows to keep an original C++ “legacy” implementation of the pass, which is used if the compiler is not built with libswift.
This is the initial version of a buildable SIL definition in libswift.
It defines an initial set of SIL classes, like Function, BasicBlock, Instruction, Argument, and a few instruction classes.
The interface between C++ and SIL is a bridging layer, implemented in C.
It contains all the required bridging data structures used to access various SIL data structures.
This showed up when trying to convert swift-package-manager to build
using static linking on Windows. We would not correctly identify the
module as being static due to there being no DeclContext for emission.
Clarify the API. Make it suitable for use everywhere in the
compiler. We should try to standardize on it and allow it to do the
OSSA fixup more often.
Add InstructionDeleter::updatingIterator() factory so we never
normally need to use InstModCallbacks.
Fix bugs in which notifyWillBeDeleted() was being called on invalid
SIL. The bugs are easily exposed just by removing copy_value side
effects, but that will be in the follow-up commit.
Call notifyWillBeDeleted() only when identifying new dead instructions
that the client may not know about. Give the client control over
force-deleting instructions. When doing its own lifetime fixups, the
client may force-delete a set of related instructions. Invoking
callbacks for these force-deleted instructions is wrong.
TODO: partial_apply support is only partial. I disabled the buggy
cases. This should be easy to fix but requires designing some
InstructionDeleter test cases.

It's not needed anymore with delayed instruction deletion.
It was used for two purposes:
1. For analysis, which cache instructions, to avoid dangling instruction pointers
2. For passes, which maintain worklists of instructions, to remove a deleted instructions from the worklist. This is now done by checking SILInstruction::isDeleted().
When an instruction is "deleted" from the SIL, it is put into the SILModule::scheduledForDeletion list.
The instructions in this list are eventually deleted for real in SILModule::flushDeletedInsts(), which is called by the pass manager after each pass run.
In other words: instruction deletion is deferred to the end of a pass.
This avoids dangling instruction pointers within the run of a pass and in analysis caches.
Note that the analysis invalidation mechanism ensures that analysis caches are invalidated before flushDeletedInsts().
Yield types are not represented in the AST FunctionType, so when we compute
the lowered type of a witness thunk for a 'modify' or 'read' coroutine, we
have to compute the yield type from scratch.
We do this by applying the witness substitutions computed by Sema to the
storage type, and then canonicalizing the resulting substituted type with
respect to the storage's own generic signature.
However, the right hand sides of the witness substitutions are written with
respect to the conformance context, which might be a subclass of the class
that the storage is originally defined in.
By not using the generic signature of this subclass, we could miss associated
types of generic parameters of the base class which were made concrete in the
subclass using a 'where' clause.
Instead, let's pass down the generic signature of the witness thunk, ensuring
we always compute the correct canonical type.
Fixes rdar://problem/77737914.
For `async` function types, an actor constraint can be enforced by the callee by hopping executors,
unlike with `sync` functions, so doesn't need to influence the outward type of the function.
