Since we will construct the parameter moves at the very beginning of the
coroutine function, I am wondering if it is really possible that
`PD->isReferenced()` may be true now. And if it is not possible,
we should convert it to `assert(!PD->isReferenced());`. Please changing this
after verifying this with some actual coroutine related workloads.
