[NFCI][SimlifyCFG] simplifyOnce(): also perform DomTree validation

And that exposes that a number of tests don't *actually* manage to
maintain DomTree validity, which is inline with my observations.

Once again, SimlifyCFG pass currently does not require/preserve DomTree
by default, so this is effectively NFC.
