- Original call sites are now never modified after construction by the local
  pass.
- DSGraph::cloneInto can now optionally not clone the call sites
- BUDataStructures no longer has a ton of book-keeping info for a broken
  implementation of the TD data structures

the BU class.

This will be used by the IPModRef class to do stuff, eventually perhaps the
TD pass will use it also.

Speaking of the TD pass, this also eliminates the self recursive case, which
was broken, and couldn't occur anyway.
