87f2b88ada Concurrency: remove workaround for silencing UB 
The newer clang properly identifies UB on invalid pointer casts. This
was previously being silenced by suppressing the warnings. Adjust the
code to use `std::bit_cast` (or the shim implementation) to avoid the
UB in this code.

23b4c6fc34 embedded: fix specialization of associated conformance entries in witness tables 
When creating a specialized witness table, we need to get the right specialized conformance.
In IRGen don't emit associated conformance witness table entries if the protocol is not a class protocol.
In this case the associated type can never be used to create an existential. Therefore such a witness table entry is never used at runtime in embedded swift.

Fixes a compiler crash

3c8ef82963 Enable usable of Span by default 
Usage of Span was temporarily behind an experimental feature flag. Now
that SE-0447 has been accepted, remove the experimental feature flag and
allow Span usage everywhere.

b9e1cbd3ac AST: Enable -unavailable-decl-optimization on visionOS. 
Using availability domains, reimplement the algorithm that determines whether a
declaration is unavailable at runtime. The new algorithm takes ABI compatible
platforms into account, ensuring that declarations that are available on iOS do
not get treated as unreachable at runtime when compiling for visionOS.

Resolves rdar://116742214.

e47638940e AST: Introduce swift::getAvailabilityConstraintsForDecl(). 
This new query is designed to become the canonical source of information
regarding whether a declaration is available to use in a given
`AvailabilityContext`. It should be adopted as the foundational building block
for all other queries that answer more specific questions about the
availability of a specific delcaration.

The implementation of this query has been copied from a variety of sources
which should eventually be deleted once the new query has been fully adopted.

NFC.

fe138e014a AST: Track an unavailable domain instead of platform in AvailabilityContext. 
Now that most of the compiler tracks availability in terms of
AvailabilityDomain, it's time to do so in AvailabilityContext as well. This
will ensure that the compiler accurately suppresses diagnostics about a decl
being unavailable in an arbitrary domain when the context of the use is already
unavailable in that domain.

With this change, most of the special-casing for the Embedded Swift availability
domain has been removed from the compiler, outside of parsing and interface
printing.
