Paul Herman ea188fc318 Add using directives to the clang::DeclContext and fix decls for variables inside namespaces
Summary: Supports the parsing of the "using namespace XXX" and "using XXX::XXX" directives. Added ambiguity errors when it two decls with the same name are encountered (see comments in TestCppNsImport). Fixes using directives being duplicated for anonymous namespaces. Fixes GetDeclForUID for specification DIEs.

Paul Herman d628cbb999 Search variables based on clang::DeclContext and clang::Decl tree
Summary: SymbolFileDWARF now creates VarDecl and BlockDecl and adds them to the Decl tree. Then, in ClangExpressionDeclMap it uses the Decl tree to search for a variable. This fixes lots of variable scoping problems.

Tamas Berghammer eb882fc1f8 Add basic fission support to SymbolFileDWARF
* 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
  where applicable

Greg Clayton f73034f99a Use LLVM casting for TypeSystem so you can cast it to subclasses.
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.

Jim Ingham 0e0984eebb Move things from the LanguageRuntime that obviously belong in the new Language plugin instead.

Greg Clayton 261ac3f4b5 Made a new abstract class named "DWARFASTParser" which lives in "source/Plugins/SymbolFile/DWARF":
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 *
    ParseFunctionFromDWARF (const lldb_private::SymbolContext& sc,
                            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;

    virtual lldb_private::CompilerDeclContext
    GetDeclContextContainingUIDFromDWARF (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.
