piece of the declaration. The '@' and the 'end' are separate tokens,
and require two SourceLocations to accurately track.
This change was motivated because ObjCContainerDecl::getSourceRange()
would previously not return the entire range of the declaration (the
'end' would be left off).

we look into a Scope that corresponds to a compound statement whose
scope was combined with the scope of the function that owns it. This

Also, don't automatically apply fix-it hints for notes. They're meant

for -Wsign-compare and -Wconversion, and use that coordinated logic to drive
both diagnostics. The new logic works more transparently with implicit
conversions, conditional operators, etc., as well as bringing -Wconversion's
ability to deal with pseudo-closed operations (e.g. arithmetic on shorts) to
-Wsign-compare.

deterministic and work properly with templates. Once a class that
needs a vtable has been defined, we now do one if two things:
- If the class has no key function, we place the class on a list of
classes whose virtual functions will need to be "marked" at the
end of the translation unit. The delay until the end of the
translation unit is needed because we might see template
specializations of these virtual functions.
- If the class has a key function, we do nothing; when the key
function is defined, the class will be placed on the
aforementioned list.
At the end of the translation unit, we "mark" all of the virtual
functions of the classes on the list as used, possibly causing
template instantiation and other classes to be added to the
list. This gets LLVM's lib/Support/CommandLine.cpp compiling again.

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.

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.

we'll warn with:

However, since this is just a warning, we don't provide a fix-it

- Instance variable lookup ("foo->ivar" and, in instance methods, "ivar")
- Property name lookup ("foo.prop")
- Superclasses
- Various places where a class name is required
- Protocol names (e.g., id<proto>)
This seems to cover many of the common places where typos could occur.

To make this really useful, we'll need to introduce typo correction in
many more places (wherever we do name lookup), and implement
declaration-vs-expression heuristics that cope with typos
better. However, for now this will handle the simple cases where we
already get good "unknown type name" diagnostics.
The LookupVisibleDecls functions are intended to be used by code
completion as well as typo correction; that refactoring will happen
later.

fixes PR5911.
