[PATCH] D62751: [Utils] Clean another duplicated util method.

[Alina Sbirlea via Phabricator via llvm-commits]

It appears the difference is in the way the DT updates are done.
+ at kuhar, @NutshellySima: Could you please take a look at the way the updates are done in MergeBlockIntoPredecessor vs (the removed) foldBlockIntoPredecessor? I tried to use a Lazy strategy and flush after doing all the potential merges, but the regression is still there. Can we get the same performance with the DomTreeUpdater here?
