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

#1: To be consistent with FieldDecl::getContextDecl(), which serves the same purpose.
#2: From my perspective, getContext() is too general (and used by several other classes for different purposes).

-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

better name is welcome :)

First, we got several CVR propagation cases wrong, which Eli pointed
out in PR2039.

Second, we didn't propagate address space qualifiers correctly, leading
to incorrect lowering of code in CodeGen/address-space.c.

Third, we didn't uniformly propagate the specifier in the array to the
pointer ("int[restrict 4]" -> "int *restrict").

This adds an ASTContext::getArrayDecayedType member that handles the 
non-trivial logic for this seemingly simple operation.

Fairly large "cleaup" related to changing ObjCCompatibleAliasDecl superclass (to inherit from NamedDecl, instead of ScopedDecl). 

- Added a DenseMap to associate an IdentifierInfo with the ObjCCompatibleAliasDecl.
- Renamed LookupScopedDecl->LookupDecl and changed it's return type to Decl. Also added lookup for ObjCCompatibleAliasDecl's.
- Removed Sema::LookupInterfaceDecl(). Converted clients to used LookupDecl().
- Some minor indentation changes.

Will deal with ObjCInterfaceDecl and getObjCInterfaceDecl() in a separate commit...

Fix objc ivar lookup.  Ivar lookup should occur between lookup
of method-local values and lookup of globals.  Emulate this with
some logic in the handling of Sema::ActOnIdentifierExpr.

Two todo's left:
 1) sema shouldn't turn a bare reference to an ivar into "self->ivar"
    in the AST.  This is a hack.
 2) The new ScopedDecl::isDefinedOutsideFunctionOrMethod method does
    not correctly handle typedefs and enum constants yet.

it would get filled in later.  Move the allocation+filling in to be more 
consistent with other stuff, e.g. the addMethods method.

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.
