Box::into_vec: use Box::into_raw instead of mem::forget `Box::into_raw` does, in one step, turn the `Box` into a raw ptr and avoid deallocation. Seems cleaner than separating the two. Also, `mem::forget` gets the `Box` with a `noalias` argument, but it is not actually correct that this is an exclusive pointer. So a stricter version of Stacked Borrows would complain here. (I can't actually make Stacked Borrows that strict yet though due to other issues.)
