- Fix a bunch of bugs where we were doing work on nodes after they became dead
- Add support for aux function call sites
- Add support for not cloning call sites

- 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
