Put AvailabilityRange into its own header with very few dependencies so that it
can be included freely in other headers that need to use it as a complete type.
NFC.
A bunch of synthesis code was getting this wrong
and setting an interface type for a TypedPattern.
Assert that we have a contextual type, and update
some synthesis logic.
Although I don't plan to bring over new assertions wholesale
into the current qualification branch, it's entirely possible
that various minor changes in main will use the new assertions;
having this basic support in the release branch will simplify that.
(This is why I'm adding the includes as a separate pass from
rewriting the individual assertions)
The only callers of `DerivedConformance::createBuiltinCall` aren't
actually aware of what the generic signature is for the builtin they
want to call. Thus, they can't really provide the needed conformances.
This wasn't an issue when there were no conformances needed for the
substitution map, but with NoncopyableGenerics, we need at least
Copyable conformances for the generic parameters of a builtin. It's easy
enough to make this function just handle generating the conformances
list, so that's the refactoring here.
For any operation that can throw an error, such as calls, property
accesses, and non-exhaustive do..catch statements, record the thrown
error type along with the conversion from that thrown error to the
error type expected in context, as appropriate. This will prevent
later stages from having to re-compute the conversion sequences.
Parse typed throw specifiers as `throws(X)` in every place where there
are effects specified, and record the resulting thrown error type in
the AST except the type system. This includes:
* `FunctionTypeRepr`, for the parsed representation of types
* `AbstractFunctionDecl`, for various function-like declarations
* `ClosureExpr`, for closures
* `ArrowExpr`, for parsing of types within expression context
This also introduces some serialization logic for the thrown error
type of function-like declarations, along with an API to extract the
thrown interface type from one of those declarations, although right
now it will either be `Error` or empty.
This is a futile attempt to discourage future use of getType() by
giving it a "scary" name.
We want people to use getInterfaceType() like with the other decl kinds.

Eliminate the use of the type-erased `AnyActorIdentity` within the
distributed actor protocol by exposing the identity type of an actor
transport as an associated type, `Identity`, which is then used to
refer to all actors that have that transport.
Retain `AnyActorIdentity`, because it remains useful for type-erasing
actor transports, especially as the `Identity` type for
`AnyActorTransport`. For now, make it the default type of `Identity`:
this helps smooth over the transition from use of `AnyActorIdentity`,
but we might want to remove this to make use of the type-erased forms
always opt-in.
Eliminate the required use of existentials in distributed actors by
introducing the `Transport` associated type into the
`DistributedActor` protocol. Each distributed actor has a known
(concrete) actor transport type, reducing storage requirements and
transport dynamism when it isn't needed.
Distributed actors can manually specify their `Transport` associated
type or pick up a default by looking for a type named
`DefaultActorTransport`. A library that vends an actor transport can
make create a public typealias `DefaultActorTransport` referring to
its transport, so importing that library and defining a distributed
actor will use that library's transport.
Introduce a type-erased `AnyActorTransport` type to provide an
explicitly dynamic actor transport. This is still an important option,
e.g., for cases where one wants to be able to dynamically change the
transport for testing or different kinds of deployment. For now, we
default to this transport in the library (via `DefaultActorTransport`),
but we may very well want to eliminate this because it will be
ambiguous with client libraries that vend their own
`DefaultActorTransport`.
Refactor the code that generates SIL to call into the distributed actor
transport to eliminate duplication and better cope with concrete actor
transports. Centralize the knowledge of which actor transport is used
with a given distributed actor type.
This is an non-user-visible attribute that is semantically identical to
`nonisolated` except that it allows use in distributed actors. It is
only, and can only, be used for the two fields that distributed actors
have in both the local actor and in the remote proxy, "id" and
"actorTransport". So, special-case the "nonisolated" check for those
fields and stop using `@_distributedActorIndependent`.
