Make C++ classes track the POD property (C++ [class]p4)
Track the existence of a copy assignment operator.
Implicitly declare the copy assignment operator if none is provided.
Implement most of the parsing job for the G++ type traits extension.
Fully implement the low-hanging fruit of the type traits:
__is_pod: Whether a type is a POD.
__is_class: Whether a type is a (non-union) class.
__is_union: Whether a type is a union.
__is_enum: Whether a type is an enum.
__is_polymorphic: Whether a type is polymorphic (C++ [class.virtual]p1).

DeclContexts whose members are visible from enclosing DeclContexts up
to (and including) the innermost enclosing non-transparent
DeclContexts. Transparent DeclContexts unify the mechanism to be used
for various language features, including C enumerations, anonymous
unions, C++0x inline namespaces, and C++ linkage
specifications. Please refer to the documentation in the Clang
internals manual for more information.
Only enumerations and linkage specifications currently use transparent
DeclContexts.
Still to do: use transparent DeclContexts to implement anonymous
unions and GCC's anonymous structs extension, and, later, the C++0x
features. We also need to tighten up the DeclContext/ScopedDecl link
to ensure that every ScopedDecl is in a single DeclContext, which
will ensure that we can then enforce ownership and reduce the memory
footprint of DeclContext.

When emitting the static variables we need to make sure that the order is preserved.
Fix this by making StaticDecls a std::list which has O(1) random removal.

semantics and improve our handling of default arguments. Specifically,
we follow this order:
- As soon as the see the '}' in the class definition, the class is
complete and we add any implicit declarations (default constructor,
copy constructor, etc.) to the class.
- If there are any default function arguments, parse them
- If there were any inline member function definitions, parse them
As part of this change, we now keep track of the the fact that we've
seen unparsed default function arguments within the AST. See the new
ParmVarDecl::hasUnparsedDefaultArg member. This allows us to properly
cope with calls inside default function arguments to other functions
where we're making use of the default arguments.
Made some C++ error messages regarding failed initializations more
specific.

- Overloading has to cope with having both static and non-static
member functions in the overload set.
- The call may or may not have an implicit object argument,
depending on the syntax (x.f() vs. f()) and the context (static
vs. non-static member function).
- We now generate MemberExprs for implicit member access expression.
- We now cope with mutable whenever we're building MemberExprs.

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.

simple test that actually does VLA codegen.
Note that despite the fact that the alloca isn't in the entry block, it
should dominate all uses; this is guaranteed by the restrictions on goto
into VLA scope in C99.

full encoding of the class which has an ivar of pointer to this
class. Its name is encoded in the type for the ivar in the
ivar-list metadata. This patch conforms to the above rule.

* Now Bind() methods take and return GRState* because binding could
also alter GDM.
* No variables are initialized except those declared with initial
values.
* failed C test cases are due to bugs in RemoveDeadBindings(),
which removes constraints that is still alive. This will be fixed in later
patch.
* default value of array and struct regions will be implemented in later patch.
