[CoroutineAccessors] Use async bit in descriptors.
...
To facilitate back deployment, make use of the fact that the async bit
has up to now never been set for read and modify accessors and claim
that set bit to indicate that it is a callee-allocated coroutine. This
has the virtue of being completely back deployable because like async
function pointers coro function pointers must be auth'd and signed as
data.

[Concurrency] Fix race condition in _runAsyncMain.
...
As of the custom main/global executor changes, there is a race in
`_runAsyncMain()` to construct the main executor; if this goes the wrong way,
the IRGen async tests, which use this function, can fail.
Fix by explicitly constructing a task and enqueing it on the main executor,
instead of detaching a task and trying to hop to it.

[Concurrency] Avoid inserting handler record in already cancelled task. ( #80456 )
...
This avoids the potential to race with the triggering coming from
task_cancel, because we first set the cancelled flag, and only THEN
take the lock and iterate over the inserted records. Because of this we
could: T1 flip the cancelled bit; T2 observes that, and triggers
"immediately" during installing the handler record. T1 then proceeds to
lock records and trigger it again, causing a double trigger of the
cancellation handler.

Remove Malloc Type Descriptor cache ( #80355 )
...
Remove Malloc Type Descriptor cache and trivialize
`computeMallocTypeSummary()` to only provide
language. The remaining info in
`malloc_type_summary_t` are currently not used by
the allocator.
The principled, long-term solution is to have the
Swift compiler compute type descriptors for Swift
types.

we'd be scheduling Dispatch executions with the wrong clock.
