Jon Roelofs bdd17b853f Remove a reference to rdar://problem/10664933 ...

The original commit, and the comments in the code already provide sufficient
context. But for posterity, there's a tiny bit more that might be useful if
someone is digging here in the future:

> This is related to <rdar://problem/10318439> Lower invokes into terminating
> machine instructions.
>
> The return value from a function call is live in to that function call's
> landing pad. The landing pad is shared with a later call, and the variable is
> undef on the first exceptional edge.
>
> Our computation of the last legal split point gets confused because the
> return value is live-out from the calling block, and live-in to the landing
> pad, but it is not live on the edge itself.
>
> Fixed in r147911 and r147912.
