Can we make any member function that has an addressspace cast on the implicit
object also `alwaysinline` at the call site? That would allow us to side-step
any issues with `noinline`.
To avoid the language being completely unwieldy I think we're going to need to
support some mechanism for allowing implicit objects in different address
spaces.
