The IsolatedConformances feature moves to a normal, supported feature.
Remove all of the experimental-feature flags on test cases and such.
The InferIsolatedConformances feature moves to an upcoming feature for
Swift 7. This should become an adoptable feature, adding "nonisolated"
where needed.

This is going to need a proper implementation in the requirement
machine. For the moment, provide a slightly-less-broken implementation
but leave a test case where we incorrectly accept racey code.

Seems that during refactorings of child cancellations we somehow missed
also cancelling the group itself. It seems we did not have good test
coverage of the addTaskUnlessCancelled somehow and thus this slipped
through.
This adds a regression test for addTaskUnlessCancelled and fixes how we
handle the cancellation effect in TaskStatus.

Because `TaskAllocator` is not a round multiple of the machine word
size on 64-bit platforms, I think we end up with padding before the
`TaskLocal::Storage` following it, which makes the `PrivateStorage`
structure larger than the calculation in `ABI/Task.h`.

We decided that using a magic typealias to set the executor factory was better
than using a compiler option. Remove the `-executor-factory` option, and replace
by looking up the `DefaultExecutorFactory` type, first in the main module, and
then if that fails in Concurrency.

Currently, the macro plugin options are included as cache key and the
absolute path of the plugin executable and library will affect cache
hit, even the plugin itself is identical.
Using the new option `-resolved-plugin-validation` flag, the macro
plugin paths are remapped just like the other paths during dependency
scanning. `swift-frontend` will unmap to its original path during the
compilation, make sure the content hasn't changed, and load the plugin.
It also hands few other corner cases for macro plugins:
* Make sure the plugin options in the swift module is prefix mapped.
* Make sure the remarks of the macro loading is not cached, as the
mesasge includes the absolute path of the plugin, and is not
cacheable.

Simply omit the 'nocapture' attribute on the parameter.
Fixes rdar://148039510 ([nonescapable] IRGen: lower addressable

Explanation: The experimental feature flag was not available for production
compilers. There is no reason for that.
Issue: rdar://148961491
Risk: Low, no functional changes other than making the flag available.

Explanation: In Swift, Escapable types cannot have non-escapable stored
properties. Unfortunately, these checks could be circumvented via C++
interop, constructing invalid Swift code. This patch errors out on
importing C++ code of this shape.
Issue: rdar://148899224
Risk: Low, the fix is fairly targeted to the affected scenario.
Testing: Added tests to test suite

When loading a module with embedded bridging header, bind the bridging
header module in the context when bridging header auto chaining is used.
This is because all the bridging header contents are chained into a PCH
file so binary module with bridging header should reference the PCH file
for all declarations.

Addressable parameters must remain indirect.
Incidentally also fixes an obvious latent bug in which all specialization was
disabled if any metatypes could not be specialized.

Iterating child tasks depends on knowing the size of AsyncTask, and changing the size of the task broke it. Instead of relying on mirroring the full structure in our out-of-process definitions, add a debug variable to libswift_Concurrency that contains the size of AsyncTask.
While we're there, add some more validation to child task enumeration. Check each child task's metadata pointer to make sure that it actually points to the AsyncTask metadata, and have the inner loop also increment and check ChildTaskLoopCount to stop runaway iteration in that loop.

ActiveTaskStatusSize is 2 words, not 4, on most targets.
PrivateStorageSize is measured in bytes, not words, so the Storage field needs to be a char[].

When serializing `@available` attributes, if the attribute applies to a custom
domain include enough information to deserialize the reference to that domain.

Introduce `PatternBindingCaptureInfoRequest`, and kick it after
contextualizing a property initializer. This ensures it gets run
for stored properties added by macro expansions.

Introduce a convenience for aborting while printing a given message
