Add QualifiedDeclRefExpr, which retains additional source-location
information for declarations that were referenced via a qualified-id,
e.g., N::C::value. We keep track of the location of the start of the
nested-name-specifier. Note that the difference between
QualifiedDeclRefExpr and DeclRefExpr does have an effect on the
semantics of function calls in two ways:
1) The use of a qualified-id instead of an unqualified-id suppresses
argument-dependent lookup
2) If the name refers to a virtual function, the qualified-id
version will call the function determined statically while the
unqualified-id version will call the function determined dynamically
(by looking up the appropriate function in the vtable).

Neither of these features is implemented yet, but we do print out
qualified names for QualifiedDeclRefExprs as part of the AST printing.

Add support for member references (E1.E2, E1->E2) with C++ semantics,
which can refer to static data members, enumerators, and member
functions as well as to non-static data members.

Implement correct lvalue computation for member references in C++.
Compute the result type of non-static data members of reference type properly.

Unifies the name-lookup mechanisms used in various parts of the AST
and separates lexical name lookup from qualified name lookup. In
particular:
* Make DeclContext the central data structure for storing and
looking up declarations within existing declarations, e.g., members
of structs/unions/classes, enumerators in C++0x enums, members of
C++ namespaces, and (later) members of Objective-C
interfaces/implementations. DeclContext uses a lazily-constructed
data structure optimized for fast lookup (array for small contexts,
hash table for larger contexts).

* Implement C++ qualified name lookup in terms of lookup into
DeclContext.

* Implement C++ unqualified name lookup in terms of
qualified+unqualified name lookup (since unqualified lookup is not
purely lexical in C++!)

* Limit the use of the chains of declarations stored in
IdentifierInfo to those names declared lexically.

* Eliminate CXXFieldDecl, collapsing its behavior into
FieldDecl. (FieldDecl is now a ScopedDecl).

* Make RecordDecl into a DeclContext and eliminates its
Members/NumMembers fields (since one can just iterate through the
DeclContext to get the fields).

Make sema and codegen allow __builtin___CFStringMakeConstantString as a valid

into EmitConstantExpr.

instead of making codegen try to know about all of the builtins to generate
constants for them, just use the constant evaluator to do the job. This
also fixes crashes on 'unknown constant builtins'.
