- Change implementation of MemRegion::hasStackStorage()/hasHeapStorage() to use
  'getMemorySpace()'.  This avoids a double traversal up the region hierarchy
  and is simpler.
- Add MemRegion::hasHeapOrStackStorage() as a slightly more efficient
  alternative to 'hasStackStorage() || hasHeapStorage()'.

- Embed a reference to MemRegionManager objects in MemSpaceRegion objects
- Use this embedded reference for MemRegion objects to access ASTContext objects without external help
- Use this access to ASTContext to simplify 'isBoundable' (no ASTContext& argument required)

- Remove the 'isFeasible' flag from all uses of 'Assume'.
- Remove the 'Assume' methods from GRStateManager.  Now the only way to
  create a new GRState with an assumption is to use the new 'assume' methods
  in GRState.

Add a type (ObjCObjectPointerType) and remove a type (ObjCQualifiedIdType).

This large/tedious patch is just a first step. Next step is to remove ObjCQualifiedInterfaceType. After that, I will remove the magic TypedefType for 'id' (installed by Sema). This work will enable various simplifications throughout clang (when dealing with ObjC types).

GRState object has a direct reference to its GRStateManager, making
the functionality of GRStateRef redunandant.  This will lead to some
nice API cleanup and code shrinking across libAnalysis.

- Add "sections" to RegionStoreManager.cpp to delineate functionality.
- Add new function "CreateFieldsOnlyRegionStoreManager" that uses the new
  RegionStoreFeatures class to use a reduced set of features from
  RegionStoreManager (in this case, only field-sensitivity). This isn't
  completely hooked up yet.
