-Added TranslationUnitDecl class to serve as top declaration context
-ASTContext gets a TUDecl member and a getTranslationUnitDecl() function
-All ScopedDecls get the TUDecl as DeclContext when declared at global scope

just as they are declared in objc classes.

Remove FileVarDecl and BlockVarDecl. They are replaced by VarDecl::isBlockVarDecl() and VarDecl::isFileVarDecl().

This is a fairly mechanical/large change. As a result, I avoided making any changes/simplifications that weren't directly related. I did break two Analysis tests. I also have a couple FIXME's in UninitializedValues.cpp. Ted, can you take a look? If the bug isn't obvious, I am happy to dig in and fix it (since I broke it).

inheritance in C++. It'll parse the base-specifier list, e.g.,

 class D : public B1, virtual public B2 { };

and do some of the simpler semantic checks (B1 and B2 are classes;
they aren't unions or incomplete types, etc).

allows the parsing of "class" in addition to "struct" and "union" to
declare a record.  So this patch allows:

 class C { };
 class C c1;

But it does not contain the lookup bits, so this won't work yet:

 C c2;

1) objc ivar processing is split out of ActOnField into its own ActOnIvar method.
2) the new objc ivar action takes visibility info directly, eliminating 
  AllVisibilities in ParseObjCClassInstanceVariables.

While it is similar to the other compatibility predicates in ASTContext,
it is not used by them and is different.

In addition, greatly simplify ObjCQualifiedIdTypesAreCompatible and
fix some canonical type bugs.  Also, simplify my Type::getAsObjC* methods.

Without this, the diagnostic is very confusing. The diag is now consistent with gcc as well.

-Added ContextDecl (no TranslationUnitDecl)
-ScopedDecl class has a ContextDecl member
-FieldDecl class has a ContextDecl member, so that a Field or a ObjCIvar can be traced back to their RecordDecl/ObjCInterfaceDecl easily
-FunctionDecl, ObjCMethodDecl, TagDecl, ObjCInterfaceDecl inherit from ContextDecl. With TagDecl as ContextDecl, enum constants have a EnumDecl as their context.
-Moved Decl class to a "DeclBase.h" along with ContextDecl class
-CurContext is handled by Sema

Change ObjCInterfaceDecl to inherit from NamedDecl (not TypeDecl). While ObjCInterfaceDecl is arguably a TypeDecl, it isn't a ScopedDecl. Since TypeDecl's are scoped, it makes sense to simply treat them as NamedDecl's. I could have fiddled a bit more with the hierarchy (in terms of creating a non-scoped TypeDecl), however this probably isn't worth the effort. 

I also finished unifying access to scope decl change by converting Sema::getObjCInterfaceDecl() to use Sema::LookupDecl(). This is much cleaner now:-)

allowing them to be treated the same in some contexts.  A suggestion for a
better name is welcome :)
