Adds sections `__TEXT,__swift_as_entry`, and `__TEXT,__swift_as_ret` that contain relative pointers to async functlets modelling async function entries, and function returns, respectively. Emission of the sections can be trigger with the frontend option `-Xfrontend -enable-async-frame-push-pop-metadata`. This is done by: * IRGen adding a `async_entry` function attribute to async functions. * LLVM's coroutine splitting identifying continuation funclets that model the return from an async function call by adding the function attribute `async_ret`. (see #llvm-project/pull/9204) * An LLVM pass that keys off these two function attribute and emits the metadata into the above mention sections. rdar://134460666
