2012195cd5 Alter the runtime interface for awaiting futures and task groups.
First, just call an async -> T function instead of forcing the caller
to piece together which case we're in and perform its own copy.  This
ensures that the task is actually kept alive properly.

Second, now that we no longer implicitly depend on the waiting tasks
being run synchronously, go ahead and schedule them to run on the
global executor.

This solves some problems which were blocking the work on TLS-ifying
the task/executor state.

4373bdd6d0 Conditionally start using llvm::CallingConv::SwiftTail for async functions
This is conditional on UseAsyncLowering and in the future should also be
conditional on `clangTargetInfo.isSwiftAsyncCCSupported()` once that
support is merged.

Update tests to work either with swiftcc or swifttailcc.

e2a8abc9e5 [Async CC] Make error indirect.
Previously, the error stored in the async context was of type SwiftError
*.  In order to enable the context to be callee released, make it
indirect and change its type to SwiftError **.

daa72d3cc5 Add llvm::Attribute::SwiftAsync to the context parameter
* Adds support for generating code that uses swiftasync parameter lowering.

* Currently only arm64's llvm lowering supports the swift_async_context_addr intrinsic.

* Add arm64e pointer signing of updated swift_async_context_addr.

This commit needs the PR llvm-project#2291.

* [runtime] unittests should use just-built compiler if the runtime did

This will start to matter with the introduction of usage of swiftasync parameters which only very recent compilers support.
