Revamp the "CSEMap" datastructure used in the SelectionDAG class. This
eliminates a bunch of std::map's in the SelectionDAG, replacing them with a
home-grown hashtable.
This is still a work in progress: not all the maps have been moved over and the
hashtable never resizes. That said, this still speeds up llc 20% on kimwitu++
with -fast -regalloc=local using a release build.
