Implement FIXME in GRExprEngine::VisitUnaryOperator() to handle implicit conversions caused by the '!' operator.  This required adding some logic to GRSimpleVals to reason about nonloc::LocAsInteger SVals.  This code appears to work fine, but it should eventually be cleaned up.

Rename ValueStateManager -> GRStateManager.

llvm-svn: 54721

Renamed deterministic EvalBinOp to DetermEvalBinOpNN.  This name mangling is unfortunately needed because virtual methods with the same name can be hidden by subclasses.

llvm-svn: 53751

Modified the new EvalBinOpNN to generate states instead of nodes.  This is a much simpler interface and is what clients will want to do.

llvm-svn: 53750

Begin major changes to EvalXXX methods in GRTransferFuncs.  Currently some of the methods only return an RVal; we want them to be able to create an arbitrary number of states.

llvm-svn: 53739

current store implementation is now encapsulated by BasicStore.

These changes prompted some long due constification of ValueState. Much of the
diffs in this patch include adding "const" qualifiers.

llvm-svn: 53423

represent possible stores to "Unknown."
