15894b791b Various fixes to symbols used for Obj-C x86_64 metadata. 
- Changed method names to match gcc (categories names still aren't
   mangled in).

 - Expose correct name for class and metadata symbols (although
   -fvisibility=hidden isn't yet correct).

 - Remove several things from llvm.used that didn't need to be there
   (I suspect this can still be trimmed).

 - Don't use asm-prefix extension for _objc_empty_{cache,vtable} (not
   needed).

 - Hide EH type class info with -fvisibility=hidden

 - Change setGlobal[Option]Visibility to not change the visibility of
   functions with internal linkage.

66afeb5968 Some "prep" work for handling ObjC @-string constants that contain UTF-8. No functionality change. 
Changed GenerateConstantString() to take an ObjCStringLiteral (instead of a std::string). While this isn't strictly necessary, it seems cleaner and allows us to cache to "containsNonAscii" if necessary (to avoid checking in both Sema and CodeGen).

a374b68b5a Back out the patch in r66302, and re-fix it properly. We assume for 
performance that the type of the returned llvm::Value for an expression

sorts of errors and silent miscompilations.

76b7acc49f First cut at zero-cost EH support. 
- Still manually generates the EH code; the parts related to cleanup

b76051534c Several cleanups: 
- rename isObjCIdType/isObjCClassType -> isObjCIdStructType/isObjCClassStructType. The previous name didn't do what you would expect.
- add back isObjCIdType/isObjCClassType to do what you would expect. Not currently used, however many of the isObjCIdStructType/isObjCClassStructType clients could be converted over time.
- move static Sema function areComparableObjCInterfaces to ASTContext (renamed to areComparableObjCPointerTypes, since it now operates on pointer types).

6e6ad602e5 Remove ScopedDecl, collapsing all of its functionality into Decl, so 
that every declaration lives inside a DeclContext.

Moved several things that don't have names but were ScopedDecls (and,
therefore, NamedDecls) to inherit from Decl rather than NamedDecl,
including ObjCImplementationDecl and LinkageSpecDecl. Now, we don't
store empty DeclarationNames for these things, nor do we try to insert
them into DeclContext's lookup structure.

The serialization tests are temporarily disabled. We'll re-enable them
once we've sorted out the remaining ownership/serialiazation issues
between DeclContexts and TranslationUnion, DeclGroups, etc.

ffca3a21f1 Provide a new kind of iterator, the specific_decl_iterator, that

considerably. It has no measurable performance impact.

91f84216f7 Unifies the name-lookup mechanisms used in various parts of the AST 
and separates lexical name lookup from qualified name lookup. In
particular:
  * Make DeclContext the central data structure for storing and
    looking up declarations within existing declarations, e.g., members
    of structs/unions/classes, enumerators in C++0x enums, members of
    C++ namespaces, and (later) members of Objective-C
    interfaces/implementations. DeclContext uses a lazily-constructed
    data structure optimized for fast lookup (array for small contexts,
    hash table for larger contexts). 

  * Implement C++ qualified name lookup in terms of lookup into
    DeclContext.

  * Implement C++ unqualified name lookup in terms of
    qualified+unqualified name lookup (since unqualified lookup is not
    purely lexical in C++!)

  * Limit the use of the chains of declarations stored in
    IdentifierInfo to those names declared lexically.

  * Eliminate CXXFieldDecl, collapsing its behavior into
    FieldDecl. (FieldDecl is now a ScopedDecl).

  * Make RecordDecl into a DeclContext and eliminates its
    Members/NumMembers fields (since one can just iterate through the
    DeclContext to get the fields).
