Tim Northover b613f8842e DeadArgElim: arguments affect all returned sub-values by default. ...

Unless we meet an insertvalue on a path from some value to a return, that value
will be live if *any* of the return's components are live, so all of those
components must be added to the MaybeLiveUses.

Previously we were deleting arguments if sub-value 0 turned out to be dead.
