* Create new dwo symbol file class
* Add handling for .dwo sections
* Change indexes in SymbolFileDWARF to store compile unit offset next to
DIE offset
* Propagate queries from dwarf compile unit to the dwo compile unit

This will keep our code cleaner and it removes the need for intrusive additions to TypeSystem like:
class TypeSystem
{
virtual ClangASTContext *
AsClangASTContext() = 0;
}
As you can now just use the llvm::dyn_cast and other casts.

class DWARFASTParser
{
public:
virtual ~DWARFASTParser() {}
virtual lldb::TypeSP
ParseTypeFromDWARF (const lldb_private::SymbolContext& sc,
const DWARFDIE &die,
lldb_private::Log *log,
bool *type_is_new_ptr) = 0;
virtual lldb_private::Function *

const DWARFDIE &die) = 0;
virtual bool
CompleteTypeFromDWARF (const DWARFDIE &die,
lldb_private::Type *type,
lldb_private::CompilerType &clang_type) = 0;
virtual lldb_private::CompilerDeclContext
GetDeclContextForUIDFromDWARF (const DWARFDIE &die) = 0;

};
We have one subclass named DWARFASTParserClang that implements all of the clang specific AST type parsing. This keeps all DWARF parsing in the DWARF plug-in. Moved all of the DWARF parsing code that was in ClangASTContext over into DWARFASTParserClang.
lldb_private::TypeSystem classes no longer have any DWARF parsing functions in them, but they can hand out a DWARFASTParser:
virtual DWARFASTParser *
GetDWARFParser ()
{
return nullptr;
}
This keeps things clean and makes for easy merging when we have different AST's for different languages.
