This includes changing the feature name so that compilers with the experimental feature don’t accidentally pick up content that only works in the final version.
Resolves rdar://150065196.
Importing C++ class templates in symbolic mode has proven to be problematic in interaction with other compiler features, and it isn't used widely. This change removes the feature.

Guard against condfails when older compilers get a swift interface
that uses `@extensible` attribute. The attribute itself doesn't
have any effect in swift interfaces yet since all of the public
enums are already resilient in that mode.
It has indirect effects on the accessors, so it shouldn’t matter, but we can defensively redirect the query to the API counterpart anyway.
This was the last `InferredInABIAttr` attribute, so we can now remove all of the infrastructure involved in supporting attribute inference.
The "featues" part was never actually implemented and Swift Driver
is replying on information about arguments, so instead of removing
this mode, let's scope it down to "arguments" to be deprecated in
the future.
This is a replacement for `-emit-supported-features` that prints
all of the upcoming/experimental features supported by the compiler
with some additional meta information in JSON format to stdout.
Add a new language feature to avoid the stdlib’s swiftinterface becoming unintelligible to outdated compiler builds due to the generalization of Builtin.is_same_metatype.

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.
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.

Function types aren't always trivially copyable, e.g. with address-discriminated signed pointers on ARM64e. Introduce a function_cast helper and use that instead.
For now the semantics provided by `@extensible` keyword on per-enum
basis. We might return this as an upcoming feature in the future with
a way to opt-out.
Otherwise, referring to swift_ASTGen_bridgedSwiftClosureCall_1 results in
a linker error on a bootstrap build (i.e., without Swift host tools
available).
Introduce a convenience for aborting while printing a given message
to a frame of the pretty stack trace. Use this in the existing places
where we're currently doing this.
Building on top of PR #79288, this update synthesizes a static factory method using the default new operator, with a call to the default constructor expression for C++ foreign reference types, and imports them as Swift initializers.
