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"

Fix three bugs:
...
1. Calls to external global VARIABLES should not be treated as a call to an
external function
2. Efficiently deleting an element from a vector by using std::swap with
the back, then pop_back is NOT a good way to keep the vector sorted.
3. Our hope of having stuff get deleted by making them redundant just won't
work. In particular, if we have three calls in sequence that should be
merged: A, B, C first we unify B into A. To be sure that they appeared
identical (so B would be erased) we set B = A. On the next step, we
unified C into A and set C = A. Unfortunately, this is no guarantee that
C = B, so we would fail to delete the dead call. Switch to a more
explicit scheme.

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.

Move the stuff that fixes the size, orientation & fonts of graphs to

the debugging functions that call "dot". These fixed settings have
various problems: for example, the fixed size that is set in the graph
traits classes is not appropriate for turning the dot file into a PNG,
and if TrueType font rendering is being used, the 'Courier' TrueType font
may not be installed. It seems easy enough to specify these things on the
command line, anyhow.

Two changes:
...
1. Functions do not make things incomplete, only variables
2. Constant global variables no longer need to be marked incomplete, because
we are guaranteed that the initializer for the global will be in the
graph we are hacking on now. This makes resolution of indirect calls happen
a lot more in the bu pass, supports things like vtables and the C counterparts
(giant constant arrays of function pointers), etc...
Testcase here: test/Regression/Analysis/DSGraph/constant_globals.ll

Instead of cloning the globals for main into the globals graph at the end of

BU propagation, clone the globals into the GG of EACH FUNCTION that finishes
