Ted Kremenek 2bdd77696e 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.

Ted Kremenek c156f1ffc6 Fixed a horribly insidious bit-masking bug in the implementation of
ExplodedNode that would occasionally result in heap corruption.

Ted Kremenek 3f06864c25 Fixed subtle caching bug in ExplodedGraph that would cause some nodes to
be incorrectly merged together.

Ted Kremenek e81734b01c Simplified transfer function logic for ++/-- operators.
Added more boilerplate transfer function support for pointer arithmetic.
Added more pretty-printing support for symbolic constraints.
Added transfer function support for handling enum values.
Minor pointer types cleanup in ExplodedGraphImpl.

Ted Kremenek e914bb8183 Fixed iterator bug in ExplodedNodeImpl::NodeGroup::end(); we would improperly
handle the case where the number of nodes was 0.

Fixed bug in GREngineImpl where we did not proceed to the next statement
when processing a PostStmt location.

Ted Kremenek deac51943a Fixed bug in cleanup of nodes in ExplodedNodeImpl where we should directly
call the dstor instead of using delete.

Ted Kremenek d122bbdb06 Moved destructor logic of templated class ExplodedGraph to non-templated
parent class ExplodedGraphImpl.

Ted Kremenek eb370bc386 Created ExplodedGraph.cpp and moved most method implementations of
ExplodedNodeImpl::NodeGroup from being defined inline to being defined
"out-of-line" in ExplodedGraph.cpp. This removes a dependence on including
<vector> in ExplodedGraph.h, and will hopefully result in smaller generated code
with negligible performance impact.
