    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.

class BUDataStructure::CallSite is no longer needed here.

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

  * 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.
