"Method accepting NSError** argument should have non-void return value to indicate that an error occurred."
Test case written, but the header needs to be delta-debugged reduced. Will commit shortly.

if we know that 'len != 0' and know that 'i == 0' then we know that
'i < len' must evaluate to true and cannot evaluate to false

motivated because it became clear that the number of subclasses of ProgramPoint
would expand and we ran out of bits to represent a pointer variant. As a plus of
this change, BlockEdge program points can now be represented explicitly without
using a cache of CFGBlock* pairs in CFG.

"Here is a patch what replaces std::ostream with llvm::raw_ostream. This patch
covers the AST library, but ignores Analysis lib."

- Change definition of store::Region and store::Binding (once again) to make
them real classes that just wrap pointers. This makes them more strictly
typed, and allows specific implementations of Regions/Bindings to just
subclass them.
- minor renamings to RegionExtent and its subclasses
- added a bunch of doxygen comments
StoreManager: (static analyzer)
- added 'iterBindings', an iteration method for iterating over the bindings of a
store. It that takes a callback object (acting like a poor man's closure).
- added 'getRVal' version for store::Binding. Will potentially phase the other
versions of GetRVal in StoreManager out.
- reimplemented 'getBindings' to be non-virtual and to use 'iterBindings'
BasicStoreManager: (static analyzer)
- implemented 'iterBindings' for BasicStoreManager

Migrated CFRefCount.cpp to use getBindings and BindingsAsString instead of
making assumptions about the Store (removed dependence on GRState::vb_iterator).

Their precise semantics will be implemented by a specific StoreManager.
Use function pointer to create the StoreManager in GRStateManager. This matches how we create ConstraintsManager.

an APInt directly to an ostream now, so add some hacks. It would
be better to switch all of the bugreport (and friends) stuff over
to raw_ostream.

This patch extends BasicStoreManager::getInitialStore() to include code that symbolicates input variables.
It also removes redundant handling of ImplicitParamDecl, since it is a subclass of VarDecl.

- Remove ConstNotEq from GRState/GRStateManager (!= tracking uses GDM instead).
- GRStateManager now can book-keep "contexts" (e.g., factory objects) for uses
with data elements stored into the GDM.
- Refactor pretty-printing of states to use GRState::Printer objects
exclusively. This removed a huge amount of pretty-printing logic from
GRExprEngine.
CFRefCount
- Simplified some API calls based on refinements to the GDM api.

of using CheckerState).
Removed CheckerState from GRState.
Added class GRStateRef which wraps GRState* and GRStateManager*. This is handy
for generating new states with a single handle.
Added member template set/get functions to GRStateRef/GRState/GRStateManager for
accessing the Generic Data Map.
