Andrew Trick e9d0b08706 Add utilities to support OSSA update after running SSAUpdater. ...

This directly adds support to BasicBlockCloner for updating OSSA.

It also adds a much more general-purpose GuaranteedPhiBorrowFixup
utility which can be used for more complicated SSA updates, in which
multiple phis need to be created. More generally, it handles adding
nested borrow scopes for guaranteed phis even when that phi is used by
other guaranteed phis.
