26878c98de [Concurrency] Add functions to allow testing of external executors. 
Added a couple of functions to allow for the testing of executors that
aren't implemented inside the concurrency runtime itself.

606f7693d4 MandatoryPerformanceOptimizations: don't de-virtualize a generic class method call to specialized method 
This results in wrong argument/return calling conventions.
First, the method call must be specialized. Only then the call can be de-virtualized.
Usually, it's done in this order anyway, because the `class_method` instruction is located before the `apply`.
But when inlining functions, the order (in the worklist) can be the other way round.

Fixes a compiler crash.

30f0fa8d75 [Concurrency] SE-0463: Sendable inference on sync and async variants of imported APIs should match 
This is a follow-up to https://github.com/swiftlang/swift/pull/82085
which made it so async variant doesn't get `@Sendable` inferred because
the proposal specified that inference should happen only on completion
handler parameter type of a synchronous variant of an imported API.

This runs into implementation issues related to thunking in some
cases were async convention expects the type of a completion handler
to match exactly for both variants of the imported API.

451f309935 build with 64-bit time_t on 32-bit platforms (#82595) 
It is good practice to build with 64-bit `time_t`/timeval on 32-bit
platforms to avoid the Y2038 issue. This is the default when building on
Yocto for armv7, for example. Unfortunately `suseconds_t` is not an
alias to a type of the correct width (unlike time_t).

Question: on release/6.1, tv_usec is assumed to be `Int32`, but on main
it is `Int`, but appears to be the same commit hash?

7789a0ce64 [SE-0371] Back-deploy support for main-actor-isolated deinit 
When targeting a platform that predates the introduction of isolated
deinit, make a narrow exception that allows main-actor-isolated deinit
to work through a special, inlineable entrypoint that is
back-deployed. This implementation

  1. Calls into the real implementation when available, otherwise
  2. Checks if we're on the main thread, destroying immediately when
we are, otherwise
  3. Creates a new task on the main actor to handle destruction.

This implementation is less efficient than the implementation in the
runtime, but allows us to back-deploy this functionality as far back
as concurrency goes.

Fixes rdar://151029118.

907606ef28 [Serialization] A temporary fix for LocatableType 
Gracefully handle `LocatableType` types if they show up during
serialization. This is a temporary fix until we can remove
`TransitivelyConformsTo` constraint from the solver which is
the underlying cause of the issue (see https://github.com/swiftlang/swift/pull/82541).
