b541e0299e [concurrency] Deprecate some source compatibility APIs in swift 5 and obsolete in swift 6. 
These APIs remained to preserve source compatibility during bringup. We do not
want them used in swift 6 mode... so deprecate in swift 5 and obsolete in swift
6.

a43abe6a90 [Concurrency] Remove OPTNONE workaround for old clang version 
This reverts c07aa9c425 which was done to
avoid a crash in optimnized caused by this PR:
https://github.com/apple/swift/pull/41088

Since this was almost 2 years ago, we probably don't have this issue
anymore as far as I can see other resolved issues, so try to remove the
workaround.

61d00cacd6 Concurrency: Fix default type witness for AsyncSequence.Failure 
Setting this to Self.AsyncIterator.Failure doesn't work because
we replace it with its reduced type Self.Failure, and then if
you run a binary compiled against an older version of the stdlib
that does not declare the Failure associated type, we hit
infinite recursion while instantiating the witness table and
trying to populate the default type witness.

Instead, let's set the default to `any Error`. Associated type
inference is already smart enough to infer the type witness from
the AsyncIterator's Failure type; we don't need to rely on the
default mechanism for that.

Fixes rdar://129605725.

fe66c47b8a [docs] Provide more documentation on custom executors with global actors 
It could be confusing to adopters who were led to believe by the types
that they should "just" implement the sharedUnownedExecutor property,
but insead they have to implement the unownedExecutor on the specific
actor type.

Adding documentation clarify this as well as a simple test that
exercises this explicitly; We seem to have much coverage of main actor,
but not so much of custom executor global actors.

ce1dd43395 [sending] Change CheckedContinuation/AsyncThrowingStream.Continuation APIs to use sending parameters and results. 
Specifically:

1. CheckedContinuation.resume now takes a sending parameter.
2. Async{Throwing,}Stream.yield takes a sending parameter.
3. withCheckedContinuation returns a transferring parameter.

Importantly due to the previous changes around mangling, this is a mangling
neutral change.

d3e7b5116f In the task-to-thread model of UnsafeContinuation, destroy the 
condvar before we try to tail-call.  This is necessary because the
swiftasync tail-call handling is (reasonably) reluctant to reorder
cleanups so that locals are destroyed before the call, and of course it
cannot destroy them after it and still emit a tail call.

Old versions of clang handled these tailcalls differently and failed
to diagnose this, but I'm pretty sure they just ended up not doing a
tail call rather than actually doing anything reasonable.
