no viable overloads. Use a different message when the class provides
no operator[] overloads at all; use it for operator(), too.
Partially addresses PR 5900.

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
improves typo correction in many common cases.

corresponding @interface, provide a note showing which interface we're
referring to. This note has the fix-it hint on it.
Also, don't automatically apply fix-it hints for notes. They're meant
to express fix-its that would change semantics.

template instantiations with strong external linkage rather than with
weak ODR linkage.

before we had seen the (delayed) inline body.

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.
Fixes PRs 5887, 5937, 5938, and 5939.

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.

the same intended semantics as used in folding conditional operators.

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.

statements are used.
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!

constructs:
- 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.
