Fix the "partial pool allocator" on em3d and others. The problem is that
...
DSNodes, unlike other GraphTraits nodes, can have null outgoing edges, and
df_iterator doesn't take this into consideration. As a workaround, the
successor iterator now handles null nodes and 'indicates' that null has
no successors.

Substantially improve the DSA code by removing 'forwarding' nodes from

DSGraphs while they are forwarding. When the last reference to the forwarding
node is dropped, the forwarding node is autodeleted. This should simplify
removeTriviallyDead nodes, and is only (efficiently) possible because we are
using an ilist of dsnodes now.

(1) Added DSGraph::cloneReachableSubgraph and DSGraph::cloneReachableNodes
...
to clone the subgraph reachable from a set of root nodes, into the
current graph, merging the global nodes into those in the current graph.
(2) Added DSGraph::updateFromGlobalGraph() to rematerialize nodes from the
globals graph into the current graph in both BU and TD passes.
(3) Added hash_set<const GlobalValue*> InlinedGlobals: a set of globals to
track which globals have been inlined into the current graph from
callers or callees. In the TD pass, such globals are up-to-date and
do not need to be rematerialized from the GlobalsGraph.
(4) Added StripIncompleteBit/KeepIncompleteBit to remove incomplete bit
when cloning nodes into the globals graph.

Checkin of new alias analysis interface:

This is a substantial rewrite of the AliasSetTracker class which now uses
...
a union-find based algorithm, is significantly faster, and is more general.
It will also scale to handle call instructions correctly, which is a nice
added bonus.
This includes a new pass -print-alias-sets which can be used to show how
alias sets are formed for a particular analysis.
