54feb84489 When building a PCH file, don't perform end-of-translation-unit
wrap-up (e.g., turning tentative definitions into definitions). Also,
very that, when we actually use the PCH file, we get the ride code
generation for tentative definitions and definitions that show up in
the PCH file.

1a0d0b9acc When writing a PCH file, keep track of all of the non-static,
non-inline external definitions (and tentative definitions) that are
found at the top level. The corresponding declarations are stored in a
record in the PCH file, so that they can be provided to the
ASTConsumer (via HandleTopLevelDecl) when the PCH file is read.

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.

33d29b3eae Add --disable-free flag to clang.
- Disables the freeing of the ASTContext and the TranslationUnit
   after parsing & sema.
 - Primarily for timing the impact on -fsyntax-only timings.

56fdb6ae69 More #include cleaning
- Kill unnecessary #includes in .cpp files. This is an automatic
   sweep so some things removed are actually used, but happen to be
   included by a previous header. I tried to get rid of the obvious
   examples and this was the easiest way to trim the #includes in one
   fell swoop.
 - We now return to regularly scheduled development.

dcb5e38927 ParseAST now never releases the passed ASTConsumer. This is the responsibility of the client.
The motivation is that clients may either:

(a) query the ASTConsumer object after AST parsing to collect data/etc.
(b) reuse the ASTConsumer.

380df93fd6 Added "InitializeTU" to ASTConsumer. This is used by Sema::ParseAST to pass a
TranslationUnit object instead of an ASTContext. By default it calls
Initialize(ASTConstext& Context) (to match with the current interface used by
most ASTConsumers).

Modified the ObjC-Rewriter to use InitializeTU, and to tell the TranslationUnit
to not free its Decls.  This is a workaround for: <rdar://problem/5966749>

ce20e8fe8d Try to plug some memory leaks...
1) Sema::ParseAST now constructs a TranslationUnit object to own the top-level Decls, which releases the top-level Decls upon exiting ParseAST.

2) Bug fix: TranslationUnit::~TranslationUnit handles the case where a Decl is added more than once as a top-level Decl.

3) Decl::Destroy is now a virtual method, obviating the need for a special dispatch based on DeclKind.

3) FunctionDecl::Destroy now releases its Body using its Destroy method.

4) Added Stmt::Destroy and Stmt::DestroyChildren, which recursively delete the child ASTs of a Stmt and call their dstors.  We may need to special case dstor/Destroy methods for particular Stmt subclasses that own other dynamically allocated objects besides AST nodes.

5) REGRESSION: We temporarily are not deallocating attributes; a FIXME is provided.

7a51313d8a Make a major restructuring of the clang tree: introduce a top-level
lib dir and move all the libraries into it.  This follows the main
llvm tree, and allows the libraries to be built in parallel.  The
top level now enforces that all the libs are built before Driver,
but we don't care what order the libs are built in.  This speeds
up parallel builds, particularly incremental ones.
