Andrew Trick ab42f753f7 Remove OperandOwnership::NestedBorrow. ...

Now that OperandOwnership determines the operand constraints, it
doesn't make sense to distinguish between Borrow and NestedBorrow at
this level. We want these uses to automatically convert between the
nested/non-nested state as the operand's ownership changes. The use
does not need to impose any constraint on the ownership of the
incoming value.

For algorithms that need to distinguish nested borrows, it's still
trivial to do so.
