rewrite @class declarations that showed up within linkage
specifications because those @class declarations never made it any
place where the rewriter could find them.

Moved all of the ObjC*Decl nodes over to ScopedDecls, so that they can
live in the appropriate top-level or transparent DeclContext near the
top level, e.g., TranslationUnitDecl or LinkageSpecDecl. Objective-C
declarations now show up in a traversal of the declarations in a
DeclContext (they didn't before!). This way, the rewriter finds all
Objective-C declarations within linkage specifications.

Fix ObjCInterfaceDecl::Destroy and ObjCProtocolDecl::Destroy to iterate and destroy all contained ObjCMethodDecls in one sweep.  This fixes a use-after-free error found by valgrind.

Moved logic to Sema::ProcessPropertyDecl().

- ObjCContainerDecl's (ObjCInterfaceDecl/ObjCCategoryDecl/ObjCProtocolDecl), ObjCCategoryImpl, & ObjCImplementation are all DeclContexts.
- ObjCMethodDecl is now a ScopedDecl (so it can play nicely with DeclContext).
- ObjCContainerDecl now does iteration/lookup using DeclContext infrastructure (no more linear search:-)
- Removed ASTContext argument to DeclContext::lookup(). It wasn't being used and complicated it's use from an ObjC AST perspective.
- Added Sema::ProcessPropertyDecl() and removed Sema::diagnosePropertySetterGetterMismatch().
- Simplified Sema::ActOnAtEnd() considerably. Still more work to do.
- Fixed an incorrect casting assumption in Sema::getCurFunctionOrMethodDecl(), now that ObjCMethodDecl is a ScopedDecl.
- Removed addPropertyMethods from ObjCInterfaceDecl/ObjCCategoryDecl/ObjCProtocolDecl.

This passes all the tests on my machine. Since many of the changes are central to the way ObjC finds it's methods, I expect some fallout (and there are still a handful of FIXME's). Nevertheless, this should be a step in the right direction.

Fix <rdar://problem/6450964> clang on xcode: Assertion failed: (RecordForDecl && "lookupFieldDeclForIvar no storage for class").

This was a recent regression caused by r61043 (related to code gen. for ivar references).

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).

assert if the name is not an identifier.  Update callers to do the right
thing and avoid this method in unsafe cases.  This also fixes an objc
warning that was missing a space, and migrates a couple more to taking
IdentifierInfo and QualTypes instead of std::strings.

a new NamedDecl::getAsString() method.

Change uses of Selector::getName() to just pass in a Selector 
where possible (e.g. to diagnostics) instead of going through
an std::string.

This also adds new formatters for objcinstance and objcclass
