[SILOptimizer] Let visitTransitiveEndBorrows take SILValues.

Browse Source 
Previously, visitTransitiveEndBorrows took BorrowedValues.  However,
there is at least one kind of borrow--namely,
unchecked_ownership_conversion insts--that is not currently permitted by
the BorrowedValue API.  The long term fix is to make BorrowedValue
handle such instructions.  For now, change visitTransitiveEndBorrows to
take SILValues so that unchecked_ownership_conversion can be passed to
the API.
