[SimplifyCFG] MergeBlockIntoPredecessor() already knows how to preserve DomTree
... so just ensure that we pass DomTreeUpdater it into it.

Fixes DomTree preservation for a large number of tests,
all of which are marked as such so that they do not regress.

The reversion apparently deleted the test/Transforms directory.

Will be re-reverting again.

a863435128 Temporarily Revert "Add basic loop fusion pass."
As it's causing some bot failures (and per request from kbarton).

This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda.
