Added --trim-path-graph to the driver to trim paths from the ExplodedGraph
that are not related to error nodes.
Fixed bug where we did not detect some NULL dereferences.
Added "ExplodedGraph::Trim" to trim all nodes that cannot transitively reach
a set of provided nodes.
Fixed subtle bug in ExplodedNodeImpl where we could create predecessor
iterators that included the mangled "sink" bit. The better fix is to integrate
this bit into the void* for the wrapped State, not the NodeGroups representing
a node's predecessors and successors.
