The CallGraphUpdater is a helper that simplifies the process of updating
the call graph, both old and new style, while running an CG-SCC pass.

The uses are, for now, contained in different commits, e.g. D70767 <https://reviews.llvm.org/D70767>.

More functionality, e.g., replace a function with a new version, is
added as we need it.
