-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

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.

list if desired, and guarantees that noone can create an
ObjCQualifiedInterfaceType with an unsorted list.

-Renamed ContextDecl -> DeclContext
-Removed DeclContext pointer from FieldDecl
-EnumDecl inherits from DeclContext, instead of TagDecl

Patch by Argiris Kirtzidis!

llvm-svn: 49261

-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

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