Make copy ctor have two versions to avoid dealing with conditional template
argument. DSCallSite ctor now takes all arguments instead of taking one
and being populated later.

used in the DS graphs. Essentially, what was vector<DSNodeHandle>
before is now a DSCallSite with the same vector, plus pointers to the
CallInst and the caller Function. The special-purpose class
BUDataStructure::CallSite is no longer needed.

* BUClosure doesn't have to worry about global nodes
* TDClosure now works with global nodes
* Reenable DNE on TD pass, now that globals work right

among other things.
* Significant rewrite of TD pass to avoid potentially N^2 algorithms if
possible. It is still not complete, but at least it's checked in now.

nor does it work very well, but I need to get it checked in before I break
the tree unintentionally.

Also, we now use a separate globals graph to hold externally visible nodes.
This changes both the bottom-up and top-down propagation so that
globals and other external objects do not have to appear in every
function, but only in functions in which they are referenced or
they can be used to access something else that is referenced.
