jdoerfert added a child revision: D70927: Introduce a CallGraph updater helper class.

With this patch new trivial edges can be added to an SCC in a CG-SCC
pass via the updateCGAndAnalysisManagerForCGSCCPass method. It shares
almost all the code with the existing
updateCGAndAnalysisManagerForFunctionPass method but it implements the
first step towards the TODOs.

This was initially part of D70927 <https://reviews.llvm.org/D70927>.
