point that covers templates and non-templates. This should eliminate
the flood of warnings I introduced yesterday.
Removed the ActOnClassTemplate action, which is no longer used.

Technically we could still do a bit more to avoid deferred generation of statics
which we know are used, but I seriously doubt this is important.

- Move Sema::ObjCQualifiedIdTypesAreCompatible(), Sema::QualifiedIdConformsQualifiedId(), and a couple helper functions to ASTContext.
- Change ASTContext::canAssignObjCInterfaces() to use ASTContext:: ObjCQualifiedIdTypesAreCompatible().
- Tweak several test cases to accommodate the new/improved type checking.

value. This is on by default, and controlled by -Wreturn-type (-Wmost
-Wall). I believe there should be very few false positives, though
the most interesting case would be:
int() { bar(); }
when bar does:
bar() { while (1) ; }
Here, we assume functions return, unless they are marked with the
noreturn attribute. I can envision a fixit note for functions that
never return normally that don't have a noreturn attribute to add a
noreturn attribute.
If anyone spots other false positives, let me know!

templates, e.g.,
template<typename T>
struct Outer {
struct Inner;
};
template<typename T>
struct Outer<T>::Inner {
// ...
};
Implementing this feature required some extensions to ActOnTag, which
now takes a set of template parameter lists, and is the precursor to
removing the ActOnClassTemplate function from the parser Action
interface. The reason for this approach is simple: the parser cannot
tell the difference between a class template definition and the
definition of a member of a class template; both have template
parameter lists, and semantic analysis determines what that template
parameter list means.
There is still some cleanup to do with ActOnTag and
ActOnClassTemplate. This commit provides the basic functionality we
need, however.

Educate GRExprEngine::VisitGraph() about 'PreStmt'.
Mark the constructor of 'PostStmt' to be explicit, preventing implicit
conversions and the selection of the wrong 'generateNode' method in
GRStmtNodeBuilder.
Constify a bunch of arguments, which falls out of the changes to ProgramPoint.

'Checker' interface. An updated test case illustrates that after calling a
function with the 'nonnull' attribute we now register the fact that the passed
pointer must be non-null. This retention of information was not possible with
the previously used GRSimpleAPICheck interface.

real. It turns out that we need to actually move all of the qualifiers
up to the array type itself, then recanonicalize the deduced template
argument type.

instead preferring to use the a region's actual type when creating
symbols and using the QualType passed to Retrieve for implicit
casting. This preprocessor logic is temporary; eventually we will
either remove region casts or keep them.
Temporarily toggle (via preprocessor directives) that SymbolicRegions
with heap storage are not undefined, but instead should be
symbolicated. If we want to model that a SymbolicRegion is
uninitialized, we can explicitly model that by binding UndefinedVal to
that region. It turns out that we want to treat most heap objects as
being defined, not the other way around.

'cast type' of a region to invalidate its binding. This only occurs
when using RegionStoreManager, as it records the cast type. I'm
currently considering removing the notion of a cast type (see
comments in code).
