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.

Reverted patch 47926 for ProgramPoint.h because it is currently buggy. May add back (fixed) later.

Updated CFGStmtVisitor to be in accord with rr47913: CallExprs are no longer (automatically) block-level expressions in the CFG.

Remove the first layer of support for "portability" warnings. This is
...
theoretically useful, but not useful in practice. It adds a bunch of
complexity, and not much value. It's best to nuke it. One big advantage
is that it means the target interfaces will soon lose their SLoc arguments
and target queries can never emit diagnostics anymore (yay). Removing this
also simplifies some of the core preprocessor which should make it slightly
faster.
Ted, I didn't simplify TripleProcessor, which can now have at most one
triple, and can probably just be removed. Please poke at it when you have
time.

Plug-in transfer function "EvalCall" now takes as an argument the current

Cleaned up typedefs involving StateTy so that we always use "StateTy*" instead of StateTy.
...
This is conceptually much cleaner, as it shows that the state is always a pointer.
It also makes it easier to marshall these values around across the internal APIs
of the path-sensitive engine.

Moved implementation of GRExprEngine::Nodify into GRStmtNodeBuilder. This will

TargetInfo objects now own the TargetInfoImpl objects they refer to.

TargetInfo::AddSecondaryTarget is now private, as it is only used during
