GRStateManager. Having these references was an abstraction violation, as they really should only be known about GRExprEngine. This change required adding a new 'ProcessAssume' callback in GRSubEngine. GRExprEngine implements this callback by calling 'EvalAssume' on all registered Checker objects as well as the registered GRTransferFunc object. llvm-svn: 92549
