b788e465 - [clang][dataflow] Model assignment to derived class from base. (#85064)

[clang][dataflow] Model assignment to derived class from base. (#85064) This is a relatively rare case, but - It's still nice to get this right, - We can remove the special case for this in `VisitCXXOperatorCallExpr()` (that simply bails out), and - With this in place, I can avoid having to add a similar special case in an upcoming patch.
