Add warning for falling off the end of a function that should return a
...
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!

Implement support for out-of-line definitions of the class members of class
...
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.

Temporarily disable most use of region casts in RegionStoreManager,
...
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.

Included is a test case for handling fields across translation units.

Add member template 'Type::getAs<T>', which converts a Type* to a respective T*.
...
This method is intended to eventually replace the individual
Type::getAsXXXType<> methods.
The motivation behind this change is twofold:
1) Reduce redundant implementations of Type::getAsXXXType() methods. Most of
them are basically copy-and-paste.
2) By centralizing the implementation of the getAs<Type> logic we can more
smoothly move over to Doug Gregor's proposed canonical type smart pointer
scheme.
Along with this patch:
a) Removed 'Type::getAsPointerType()'; now clients use getAs<PointerType>.
b) Removed 'Type::getAsBlockPointerTypE()'; now clients use getAs<BlockPointerType>.

Two changes:

allows ValueManager to use the SValuator when creating SVals.
(2) Added ValueManager::makeArrayIndex() and

that will help RegionStoreManager always have a consistent set of
SVals with the same integer size and type when reasoning about
array indices.

Handle some more fallout with the conversion of using PointerType for
...
Objective-C pointers to using ObjCObjectPointerType.
Now the checking for 'attribute ((nonnull))' in Sema doesn't emit an error when
trying to apply that attribute to a parameter that is an Objective-C pointer
(this is a regression).
To prevent this regression from occuring in the future, the 'nonnull.c' test was
moved to test/SemaObjC and renamed 'nonnull.m'. I also enhanced the tests to
show that function calls involved a NULL Objective-C pointer constant does not
trigger a warning. This is consistent with GCC, but should likely be fixed.
