Michael Gottesman 8f91b9e89a [ownership] Get rid of old entrypoint for creatingEndBorrow that takes the original value. ...

The original design was to make it so that end_borrow tied at the use level its
original/borrowed value. So we would have:

```
%borrowedVal = begin_borrow %original
...
end_borrow %borrowedVal from %original
```

In the end we decided not to use that design and instead just use:

```
%borrowedVal = begin_borrow %original
...
end_borrow %borrowedVal
```

In order to enable that transition, I left the old API for end_borrow that took
both original and borrowedVal and reimplemented it on top of the new API that
just took the borrowedVal (i.e. the original was just a dead arg).

Now given where we are in the development, it makes sense to get rid of that
transition API and move to just use the new API.
