non-inline key function of a class template instantiation, when no key
function is present, the class template instantiation itself was
instantiated with an explicit instantiation declaration (aka extern
template). I'm fairly certain that the C++0x specification gives us
this lattitude, although GCC doesn't take advantage of it.

  - All classes can have a key function; templates don't change that.
  non-template classes when computing the key function.
  - We always mark all of the virtual member functions of class
  template instantiations. 
  - The vtable for an instantiation of a class template has weak
  linkage. 

We could probably use available_externally linkage for vtables of
classes instantiated by explicit instantiation declarations (extern
templates), but GCC doesn't do this and I'm not 100% that the ABI
permits it.

Make static analysis support for C++ 'this' expression context-sensitive.  Essentially treat 'this' as a implicit parameter to the method call, and associate a region with it.

GRStateManager.  Having these references was an abstraction violation,
as they really should only be known about GRExprEngine.

This change required adding a new 'ProcessAssume' callback in
GRSubEngine.  GRExprEngine implements this callback by calling
'EvalAssume' on all registered Checker objects as well as the
registered GRTransferFunc object.

The type of code affected would be:

interface, suggest correction of typos. For example, given:

  @interface NSString
  @end

  @implementation NSstring
  @end

we'll warn with:

t.m:4:19: warning: cannot find interface declaration for 'NSstring';
    did you mean 'NSString'?
  @implementation NSstring
                  ^

However, since this is just a warning, we don't provide a fix-it
hint. Good idea, Ted!
