  Log Message:
  -----------
  Add a llvm.coro.end.async intrinsic

The llvm.coro.end.async intrinsic allows to specify a function that is
to be called as the last action before returning. This function will be
inlined after coroutine splitting.

This function can contain a 'musttail' call to allow for guaranteed tail
calling as the last action.
