pointer. Its purpose in life is to be a glorified void*, but which does not
implicitly convert to void* or other OpaquePtr's with a different UID.
Introduce Action::DeclPtrTy which is a typedef for OpaquePtr<0>. Change the
entire parser/sema interface to use DeclPtrTy instead of DeclTy*. This
makes the C++ compiler enforce that these aren't convertible to other opaque
types.
We should also convert ExprTy, StmtTy, TypeTy, AttrTy, BaseTy, etc,
but I don't plan to do that in the short term.
The one outstanding known problem with this patch is that we lose the
bitmangling optimization where ActionResult<DeclPtrTy> doesn't know how to
bitmangle the success bit into the low bit of DeclPtrTy. I will rectify
this with a subsequent patch.

specializations can be treated as a template. Finally, we can parse
and process the first implementation of Fibonacci I wrote!
Note that this code does not handle all of the cases where
injected-class-names can be treated as templates. In particular,
there's an ambiguity case that we should be able to handle (but
can't), e.g.,
template <class T> struct Base { };
template <class T> struct Derived : Base<int>, Base<char> {
typename Derived::Base b; // error: ambiguous
typename Derived::Base<double> d; // OK
};

templates, including in-class initializers. For example:
template<typename T, T Divisor>
class X {
public:
static const T value = 10 / Divisor;
};
instantiated with, e.g.,
X<int, 5>::value
to get the value '2'.

the declarations of member classes are instantiated when the owning
class template is instantiated. The definitions of such member classes
are instantiated when a complete type is required.
This change also introduces the injected-class-name into a class
template specialization.

class C {
void g(C c);
virtual void f() = 0;
};
In this case, C is not known to be abstract when doing semantic analysis on g. This is done by recursively traversing the abstract class and checking the types of member functions.

a class template. At present, we can only instantiation normal
methods, but not constructors, destructors, or conversion operators.
As ever, this contains a bit of refactoring in Sema's type-checking. In
particular:
- Split ActOnFunctionDeclarator into ActOnFunctionDeclarator
(handling the declarator itself) and CheckFunctionDeclaration
(checking for the the function declaration), the latter of which
is also used by template instantiation.
- We were performing the adjustment of function parameter types in
three places; collect those into a single new routine.
- When the type of a parameter is adjusted, allocate an
OriginalParmVarDecl to keep track of the type as it was written.
- Eliminate a redundant check for out-of-line declarations of member
functions; hide more C++-specific checks on function declarations
behind if(getLangOptions().CPlusPlus).

cleaner visitor framework.
Added a visitor for declarations, which is quite similar to the
visitor for statatements.
