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.
