Comment at: lldb/include/lldb/Symbol/TypeSystem.h:108-110
+  virtual DWARFASTParser *GetDWARFParser(SymbolFileDWARF &dwarf) {
+    return nullptr;
+  }
----------------
This part looks pretty dodgy. I'd like to avoid introducing plugin references 
in non-plugin code. It looks like this class isn't particularly clean already 
(DWARFDIE forward decl), but this seems to make the problem much worse.

Since this class already contains a `SymbolFile` pointer, maybe we could create 
some kind of a ast-parser constructing method on the SymbolFile class to avoid 
mentioning the SymbolFileDWARF directly.

If I was doing this, I'd probably try to take this one step further and merge 
the `GetDWARFParser`/`GetPDBParser` methods (whose only calls are in the 
relevant symbol file plugins) into a single `GetASTParser` method and do 
appropriate casts in the plugins themselves.
