More hacking on static analyzer diagnostics.  When emitting summary diagnostics the code paths for diagnostics involving paths or single locations are now unified.  This patch also constifies many arguments/methods that are touched by this logic, leading to a nice overall code cleanup.

two worklists: for nodes whose locations are block edges with loop terminators
and another for nodes with all other locations.  We only dequeue from the loop
worklist when the other is empty.  Exploration of the graph is still in
reverse-BFS.

lib dir and move all the libraries into it.  This follows the main
llvm tree, and allows the libraries to be built in parallel.  The
top level now enforces that all the libs are built before Driver,
but we don't care what order the libs are built in.  This speeds
up parallel builds, particularly incremental ones.

to roots.

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.

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.

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

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.
