Having a notion of an actual ProgramPointTag will aid in introspection of the analyzer's behavior.
For example, the GraphViz output of the analyzer will pretty-print the tags in a useful manner.

motivated because it became clear that the number of subclasses of ProgramPoint
would expand and we ran out of bits to represent a pointer variant. As a plus of
this change, BlockEdge program points can now be represented explicitly without
using a cache of CFGBlock* pairs in CFG.

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.
