1. Make it work correctly with anonymous unions.
2. Don't compute it if the warning isn't enabled.
3. Optimize the algorithm slightly to make it linear time in the 
case where we don't produce any warnings.

functions that return a value.  I was going to buffer the whole lot
up, but it should be easier to review if I check them in
incrementally.  Most of the forth coming changes either add a return
value, or make it impossible to return, or alter the return type.

Entity can now refer to declarations that are not visible outside the translation unit.
It is a wrapper of a pointer union, it's either a Decl* for declarations that don't
"cross" translation units, or an EntityImpl* which is associated with the specific "visible" Decl.

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

Remove Sema::LookupObjCImplementation and replace it with just calling ObjCInterfaceDecl::getImplementation().

- Introduce ASTContext::getObjCImplementation() and ASTContext::setObjCImplementation() which use a DenseMap to associate
  an interface/category with its implementation (if one exists).

- Introduce ObjCInterfaceDecl::get/setImplementation() and ObjCCategoryDecl::get/setImplementation() that use the above methods.

- Add a compiler error for when a category is reimplemented.

pointers.

Enhanced RegionStoreManager::Retrieve() to handle automatic casts when the
loaded value is different from the requested value. This should be refined over
time, but essentially we should always symbolicate locations as locations, and
convert them to non-locations on demand.

These changes now cause 'misc-ps.m' to pass again.
