the new NonisolatedNonsendingByDefault upcoming feature breaks remote
calls in distributed actors, because the expected isolation doesn't
match and the runtime swift_distributed_execute_target_resume will
crash.
This is a short term fix to unblock adopters, however preferably we
should mark the thunks as nonisolated(nonsending), though that seems to
be more involved.

When a function parameter has attached property wrappers (SE-0293) those
property wrappers are either considered "implementation" or "API" level.
Property wrappers that are implementation-level don't affect how the function
is called and therefore shouldn't be included in swiftinterfaces unless the
function's body is also printed.

We set an original expression on ErrorExpr for cases where we have
something semantically invalid that doesn't fit into the AST, but is
still something that the user has explicitly written. For example
this is how we represent unresolved dots without member names (`x.`).
We still want to type-check the underlying expression though since
it can provide useful diagnostics and allows semantic functionality
such as completion and cursor info to work correctly.

When emitting statement diagnostics for `if #available` queries, diagnose the
availability of the decls representing the referenced availability domains.
Among other things, this checks that the domains are sufficiently visible to be
used in the containing function body context.
This is an NFC change. The idea is that this will make it easier to add new
BuiltinTypeKinds. I missed this code when adding Builtin.ImplicitIsolationActor.
By adding a covered switch, we can make sure this code is updated in the
future.
It must be possible to disambiguate overloads using the module-wide Swift
language version, even in contexts that are themselves obsolete in the current
Swift language version.

Part of the Embedded Swift linkage model, this attribute ensures that
the function it applies to has a strong definition in its owning
module, and that its SIL is never serialized. That way, other modules
will not have access to its definition.
Implements rdar://158364184.
Lift the limitation of a single active diagnostic, which was a pretty
easy-to-hit footgun. We now maintain an array of active in-flight
diagnostics, which gets flushed once all them have ended.
The ASTPrinter may kick requests that may emit diagnostics, make sure
we don't attempt to recursively print the decl since that would lead
to infinite recursion when diagnosing the cycle.
Cache the result of turning a `ValueDecl` into an `AvailabilityDomain`. Use
split caching to make the common case of the decl not representing an
availability domain efficient.

This moves the functionality of 'bridgeClangModuleDependency' into a utility in the main scanner class because it relies on various objects whose lifetime is already tied to the scanner itself.
Afteri #83712 landed, let's make another try enabling addressable
parameters by default.
