Zachary Turner 754851ad80 DebugInfoPDB: Make the symbol base case hold an IPDBSession ref.
Dumping a symbol often requires access to data that isn't inside
the symbol hierarchy, but which is only accessible through the
top-level session.  This patch is a pure interface change to give
symbols a reference to the session.
