It was pointed out in Bug 40528 <https://bugs.llvm.org/show_bug.cgi?id=40528> that it is not clear whether insert/deleteEdge can be used to perform multiple updates and a comment in D57316 <https://reviews.llvm.org/D57316#1388344> reveals that the difference between several ways to update the DominatorTree is confusing.

This patch tries to address issues above.
