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.

the condidtional have compatible types, they are not necessarily the 
same type.  Therefore, we cast to the composite type.  As a hack, for 
the moment we assume that the composite type is the type of the 
left-hand expression; this isn't correct, but it's good enough for most 
purposes.

in Sema::CheckFunctionCall:

  http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20080512/005706.html
  
The bug was that the logic from the helper methods used by CheckFunctionCall
were being inverted (a subtle bug).  This would cause the parser to discard
any valid AST nodes involving several builtins (see patch).

This removes the last regression failure I'm seeing in the test suite: Analysis-Apple/NoReturn.

The expected immediate usage is in *mmintrin.h, so that they don't 
depend on the mess of gcc-inherited (and not completely implemented)
shuffle builtins.

-identifierResolver exposes an iterator interface to get all decls through the scope chain.
-The semantic staff (checking IdentifierNamespace and Doug's checking for shadowed tags were moved out of IdentifierResolver and back into Sema. IdentifierResolver just gives an iterator for all reachable decls of an identifier.

Allow member references to member references, so that .hi.hi gives you the high
quarter of a vector.  This is fairly convenient syntax for some insert/extract
operations.

Remove some unnecessary methods/types in the ExtVectorElementExpr class.

Replace Sema::CheckInitializerListTypes() with a helper class (InitListChecker) that synthesizes implicit InitListExpr's when appropriate (see InitListExpr comments in Expr.h for more details). I also moved the code to SemaInit.cpp, to help reduce clutter in SemaDecl.cpp.

NOTE: This work is incomplete and still fails many tests (as a result, it isn't enabled yet). Nevertheless, I wanted to check it in so I can work on it from home.

Implicitly defined functions were getting the DeclContext of the function where they appeared, causing the bug: http://llvm.org/bugs/show_bug.cgi?id=2266.
Fix it by making implicitly defined functions get the DeclContext of translation unit.
