Is this really a winning transformation?
fold (shl (srl x, c1), c2) -> (shl (and x, (shl -1, c1)), (sub c2, c1)) or

-refactor logic for retrieving bindings from VarDecls into
 RegionStoreManager::RetrieveVar()
- improve RegionStoreManager::CastRetrievedVal() and SimpleSValuate::EvalCastNL
  to better handle casts of values of the same canonical type as well as
  casts of LocAsInteger values.

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.

If it's in an ObjCContainerDecl, its "redeclaration" is the method definition in the corresponding ObjCImplDecl.
If it's in an ObjCImplDecl, its "redeclaration" is the method in the interface.

Use ObjCInterfaceDecl::getCategoryClassMethod() and ObjCInterfaceDecl::getCategoryInstanceMethod() for the same functionality.

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.

overflow correctly.

flags set properly.  (hasMemory is clearly irrelevant
when matching 'i', I don't understand what this was
supposed to be doing.)

accident, but generated code was wrong)
