      The inconsistency between igvn->type(addP)==InstPtr and addP->bottom_type() == Top
      when the base and the address of addP are TOP exposes the bug 6714406.

      Such inconsistency could be created in kill_dead_code() (node.cpp)
      where dead users are not killed aggressively but just put on IGVN worklist.

      Types should be consistent.
