This corresponds to the parameter-passing convention of the Itanium C++
ABI, in which the argument is passed indirectly and possibly modified,
but not destroyed, by the callee.
@in_cxx is handled the same way as @in in callers and @in_guaranteed in
callees. OwnershipModelEliminator emits the call to destroy_addr that is
needed to destroy the argument in the caller.

These x-refs might not be resolvable using regular lookup from the 'std' module as they could be instantiated/synthesized
by the clang importer. Augment the lookup logic in that case to try clang importer lookup logic that is used during
the conformance to the C++ iterator protocol.
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)
We still only parse transferring... but this sets us up for adding the new
'sending' syntax by first validating that this internal change does not mess up
the current transferring impl since we want both to keep working for now.

CountAttributedType and TypeCoupledDeclRefInfo are new Clang type
and type metadata created for types with the 'counted_by' attribute
that shouldn't be accessible from Swift right now. Hence, marking
them unreachable.
Non-error resilient call sites like this:
DeclContext *DC = MF.getDeclContext(contextID);
Can be replaced with this error tolerant alternative:
DeclContext *DC;
UNWRAP(MF.getDeclContextChecked(contextID), DC);
Use the self interface type instead of the declared interface type, to
get the right type for tuple conformances and the DistributedActor-as-Actor
abstract conformance.
Add the machinery to support suppression of inference of conformance to
protocols that would otherwise be derived automatically.
This commit does not enable any conformances to be suppressed.
