ab8544aa75 Do not do horrible things to the CBU graphs. In particular, we do NOT own 
the CBU graphs, copy them instead of hacking on the CBU graphs.

Also, instead of forwarding request from ECGraphs clients to the CBU graphs
clients, service them ourselves.

Finally, remove a broken "optimization"

b12914bfc0 'Pass' should now not be derived from by clients. Instead, they should derive 
from ModulePass.  Instead of implementing Pass::run, then should implement
ModulePass::runOnModule.

efffdc9408 As much as I hate to say it, the whole setNode interface for DSNodeHandles 
is HOPELESSLY broken.  The problem is that the embedded getNode call can
change the offset of the node handle in unpredictable ways.

As it turns out, all of the clients of this method really want to set
both the node and the offset, thus it is more efficient (and less buggy)
to just do both of them in one method call.  This fixes some obscure bugs
handling non-forwarded node handles.

c5204fb6f8 Complete rewrite of the code that merges DS graphs for equivalence classes 
of functions called at a common call site.  The rewrite inlines the
resulting graphs bottom-up on the SCCs of the CBU call graph.  It also
simplifies the merging of equivalence classes by exploiting the fact that
functions in non-trivial SCCs are already merged.

99df257910 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.

4ff0b9636d 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.

2f561384fb Eliminated the CompletedNodes argument to the cloneReachable* methods. This 
map was only used to implement a marginal GlobalsGraph optimization, and it
actually slows the analysis down (due to the overhead of keeping it), so just
eliminate it entirely.
