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).
