290fbb1d42 Hook up Sema support for attributes on Objective-C method declarations that
appear between the return type and the selector. This is a separate code path
from regular attribute processing, as we only want to (a) accept only a specific
set of attributes in this place and (b) want to distinguish to clients the
context in which an attribute was added to an ObjCMethodDecl.

Currently, the attribute 'objc_ownership_returns' is the only attribute that
uses this new feature. Shortly I will add a warning for 'objc_ownership_returns'
to be placed at the end of a method declaration.

c78d34699f PCH support for the global method pool (= instance and factory method
pools, combined). The methods in the global method pool are lazily
loaded from an on-disk hash table when Sema looks into its version of

79947a24e6 Eliminate Sema::ObjCImplementations, relying instead on name lookup. What's good for uniformity is good for PCH (or is it the other way around?).
As part of this, make ObjCImplDecl inherit from NamedDecl (since
ObjCImplementationDecls now need to have names so that they can be
found). This brings ObjCImplDecl very, very close to
ObjCContainerDecl; we may be able to merge them soon.

de9f17e943 Eliminate Sema::ObjCProtocols. Instead, we place ObjCProtocolDecls in
their own namespace (IDNS_Protocol) and use the normal name-lookup
routines to find them. Aside from the simplification this provides
(one less DenseMap!), it means that protocols will be lazily
deserialized from PCH files.

Make the code size of the selector table block match the code size of
the type and decl blocks.

3c301dc573 Sema::ActOnStartClassInterface(): Use PushOnScopeChains().
This enables class recognition to work with PCH. I believe this means we can remove Sema::ObjCInterfaceDecls and it's usage within Sema::LookupName(). Will investigate.

29bd76fd04 Eliminate the three SmallVectors in ObjCImplDecl (for instance
methods, class methods, and property implementations) and instead
place all of these entities into the DeclContext.

This eliminates more linear walks when looking for class or instance
methods and should make PCH (de-)serialization of ObjCDecls trivial
(and lazy).

d1148a7f72 Make sure to mark the interface as completed when we see an
@implementation that closes a @class delcaration.
 - I don't know how to make a test case for this, but this strengthens
   the invariants that hold internally. The functionality change here
   is the edit to SemaDeclObjC.cpp.

0ca1660129 Audit __private_extern__ handling.
- Exposed quite a few Sema issues and a CodeGen crash.

 - See FIXMEs in test case, and in SemaDecl.cpp (PR3983).

I'm skeptical that __private_extern__ should actually be a storage
class value. I think that __private_extern__ basically amounts to
  extern A __attribute__((visibility("hidden")))
and would be better off handled (a) as that, or (b) with an extra bit
in the VarDecl.

42959b2660 Change diagnostic as a result of researching <rdar://problem/6779809> missing interface name in "error: cannot declare variable inside a class, protocol or category ''.
Since ObjC 2.0 class "extensions" have a null name, the diagnostic above is actually "correct". Nevertheless, it is confusing. Decided to remove the name entirely (from my perspective, it didn't add any value). Also simplified the text of the diagnostic a bit.

5300accc7a improve location info for property stuff. In a property like this:
@property int x;

associate the location of X with the property decl, not the location
of the @.  Also, pass this info along to the synthesized ParmVarDecls
so that redefinition and other diagnostics can use it.  This eliminates
a fixme.

67f35b051b improve the 'conflicting types' diagnostics to include correct location info, now
that it is plumbed through Sema.  On a file from growl, we used to emit:

t.mi:107059:1: warning: conflicting types for 'removePluginHandler:forPluginTypes:'
- (void) removePluginHandler:(id <GrowlPluginHandler>)handler forPluginTypes:(NSSet *)extensions {
^
t.mi:105280:1: note: previous definition is here
- (void) removePluginHandler:(id <NSObject>)handler forPluginTypes:(NSSet *)types;
^

now we produce:

t.mi:107059:55: warning: conflicting parameter types in implementation of 'removePluginHandler:forPluginTypes:': 'id<NSObject>' vs 'id<GrowlPluginHandler>'
- (void) removePluginHandler:(id <GrowlPluginHandler>)handler forPluginTypes:(NSSet *)extensions {
                                                      ^
t.mi:105280:45: note: previous definition is here
- (void) removePluginHandler:(id <NSObject>)handler forPluginTypes:(NSSet *)types;
                                            ^

We still don't have proper loc info for properties, hence the FIXME.

5bbb3c8ad9 Push DeclGroup much farther throughout the compiler. Now the various
productions (except the already broken ObjC cases like @class X,Y;) in 
the parser that can produce more than one Decl return a DeclGroup instead
of a Decl, etc.

This allows elimination of the Decl::NextDeclarator field, and exposes
various clients that should look at all decls in a group, but which were
only looking at one (such as the dumper, printer, etc).  These have been
fixed.

Still TODO:

1) there are some FIXME's in the code about potentially using
DeclGroup for better location info.
2) ParseObjCAtDirectives should return a DeclGroup due to @class etc.
3) I'm not sure what is going on with StmtIterator.cpp, or if it can
   be radically simplified now.
4) I put a truly horrible hack in ParseTemplate.cpp.

I plan to bring up #3/4 on the mailing list, but don't plan to tackle
#1/2 in the short term.

83f095cc7e Introduce a new OpaquePtr<N> struct type, which is a simple POD wrapper for a
pointer.  Its purpose in life is to be a glorified void*, but which does not
implicitly convert to void* or other OpaquePtr's with a different UID.

Introduce Action::DeclPtrTy which is a typedef for OpaquePtr<0>.  Change the 
entire parser/sema interface to use DeclPtrTy instead of DeclTy*.  This
makes the C++ compiler enforce that these aren't convertible to other opaque
types.

We should also convert ExprTy, StmtTy, TypeTy, AttrTy, BaseTy, etc,
but I don't plan to do that in the short term.

The one outstanding known problem with this patch is that we lose the 
bitmangling optimization where ActionResult<DeclPtrTy> doesn't know how to
bitmangle the success bit into the low bit of DeclPtrTy.  I will rectify
this with a subsequent patch.
