So far, static arrays had to be put into a writable section, because the isa pointer and the (immortal) ref count field were initialized dynamically at the first use of such an array.
But with a new runtime library, which exports the symbols for the (immortal) ref count field and the isa pointer, it's possible to put the whole array into a read-only section. I.e. make it a constant global.

This patch adds an optional callback function member to the AST Context.
The callback gets invoked when a new module (or overlay module) gets
loaded.
This can be used for instance by other clients, such as lldb, to perform
actions when a module gets loaded, like showing progress to the end-user.

This prepares us to generalize ObjC selector collision diagnostics to also include protocols. NFC in this commit because, even though Sema and ClangImporter now try to record ObjC methods on non-`ClassDecl`s, `NominalTypeDecl::createObjCMethodLookup()` still doesn’t create ObjC method tables for them, so the calls are no-ops.
* [Distributed] dist actor always has default executor (currently)

* [DistributedActor] ok progress on getting the system via witness
* [Distributed] allow hop-to `let any: any X` where X is DistActor
* [Distributed] AST: Add an accessor to determine whether type is distributed actor
- Classes have specialized method on their declarations
- Archetypes and existentials check their conformances for
presence of `DistributedActor` protocol.
* [Distributed] AST: Account for distributed members declared in class extensions
`getConcreteReplacementForProtocolActorSystemType` should use `getSelfClassDecl`
otherwise it wouldn't be able to find actor if the member is declared in an extension.

[PreChecker] LookupDC might be null, so account for that

This ensures that opened archetypes always inherit any outer generic parameters from the context in which they reside. This matters because class bounds may bind generic parameters from these outer contexts, and without the outer context you can wind up with ill-formed generic environments like
<τ_0_0, where τ_0_0 : C<T>, τ_0_0 : P>
Where T is otherwise unbound because there is no entry for it among the generic parameters of the environment's associated generic signature.
This is going to be used by IRGen later on to make it possible to
decode arguments inside of distributed target accessor instead of
allocating additional storage.

Clang importer diagnostics that are produced as a result of a reference
in Swift code are attached to as notes to the Sema produced diagnostic
that indicates the declaration is unavailable.
Ex: Notes about why a C function import failed are attached to
the error explaining that the symbol could not be found in scope.

[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
Applies swift-experimental-string-processing#68 in regex literal type inference. Regex literals with captures will have type `Regex<Tuple{n}<Substring, {Captures...}>>`. This is a temporary thing that allows us to define generic constraints on captures. We will switch back to native tuples once we have variadic generics.
This patch introduces new diagnostics to the ClangImporter to help
explain why certain C, Objective-C or C++ declarations fail to import
into Swift. This patch includes new diagnostics for the following entities:
- C functions
- C struct fields
- Macros
- Objective-C properties
- Objective-C methods
In particular, notes are attached to indicate when any of the above
entities fail to import as a result of refering an incomplete (only
forward declared) type.
The new diangostics are hidden behind two new flags, -enable-experimental-clang-importer-diagnostics
and -enable-experimental-eager-clang-module-diagnostics. The first flag emits diagnostics lazily,
while the second eagerly imports all declarations visible from loaded Clang modules. The first
flag is intended for day to day swiftc use, the second for module linting or debugging the importer.
This reverts commit a67a0436f7, reversing
changes made to 9965df76d0.
This commit or the earlier commit this commit is based on (#40531) broke the
incremental bot.
Update the lexing implementation to defer to the
regex library, which will pass back the pointer
from to resume lexing, and update the emission to
call the new `Regex(_regexString:version:)`
overload, that will accept the regex string with
delimiters.
Because this uses the library's lexing
implementation, the delimiters are now `'/.../'`
and `'|...|'` instead of plain `'...'`.
A pack type looks a lot like a tuple in the surface language, except there
is no way for the user to spell a pack. Pack types are created by the solver
when it encounters an apply of a variadic generic function, as in
```
func print<T...>(_ xs: T...) {}
// Creates a pack type <String, Int, String>
print("Macs say Hello in", 42, " different languages")
```
Pack types substituted into the variadic generic arguments of a
PackExpansionType "trip" the pack expansion and cause it to produce a
new pack type with the pack expansion pattern applied.
```
typealias Foo<T...> = (T?...)
Foo<Int, String, Int> // Forces expansion to (Int?, String?, Int?)
```
- Frontend: Implicitly import `_StringProcessing` when frontend flag `-enable-experimental-string-processing` is set.
- Type checker: Set a regex literal expression's type as `_StringProcessing.Regex<(Substring, DynamicCaptures)>`. `(Substring, DynamicCaptures)` is a temporary `Match` type that will help get us to an end-to-end working system. This will be replaced by actual type inference based a regex's pattern in a follow-up patch (soon).
- SILGen: Lower a regex literal expression to a call to `_StringProcessing.Regex.init(_regexString:)`.
- String processing runtime: Add `Regex`, `DynamicCaptures` (matching actual APIs in apple/swift-experimental-string-processing), and `Regex(_regexString:)`.
Upcoming:
- Build `_MatchingEngine` and `_StringProcessing` modules with sources from apple/swift-experimental-string-processing.
- Replace `DynamicCaptures` with inferred capture types.
We need to modify the pointer pointing to the cancellation flag when reusing an ASTContext for code completion. This is not possible by the previous design because `TypeCheckerOptions` was `const`. Moving the cancellation flag to `ASTContext` will also allow other stages of the compiler to honor a cancellation request.
