When async closures are called with `AsyncFn`/`AsyncFnMut`, they return a coroutine that borrows from the closure. However, when they are called via `AsyncFnOnce`, we consume that closure, and cannot return a coroutine that borrows from data that is now dropped.
To work around around this limitation, we synthesize a separate by-move MIR body for calling `AsyncFnOnce::call_once` on a coroutine-closure that can be called by-ref.
To work around this limitation, we synthesize a separate by-move MIR body for calling `AsyncFnOnce::call_once` on a coroutine-closure that can be called by-ref.
This body operates identically to the "normal" coroutine returned from calling the coroutine-closure, except for the fact that it has a different set of upvars, since we must *move* the captures from the parent coroutine-closure into the child coroutine.
