New miniphase: ExpandPrivate

A late miniphase which resets private flag of all
members that are not accessed from within same class.
Replaces logic in RefChecks. Doing this late has two
advantages

 - we can use name expansion, because references are
   symbolic, so the names of symbols and references
   to them do not need to correspond anymore.
 - we can automatically correct for symbols moved in earlier
   phases (e.g. lifted out by LambdaLift).
