Rename SymbolID to SymbolRef.  This is a precursor to some overhauling of the representation of symbolic values.

ConcreteInt index for now.

CompoundVal now uses an ImmutableList<SVal> to store its set of SVals.  This change was motivated by the need to allow state-splitting in GRExprEngine::VisitInitListExpr.  As a side-benefit, we no longer need to perform any copies of SVals when creating a CompoundSVal, and the profiling of CompoundSVal is now constant time.

This removes the failure in null-deref-ps.c (test suite).

Added "nonlval::LValAsInteger" to represent abstract LVals casted to integers, allowing us to track lvals when they are casted back to pointers.

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.

This current implementation only works when both operands are concrete values; later we will add support for symbolic values.
