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.

what they're testing, but as a first step remove all instances of
"grep".

input filename so that opt doesn't print the input filename in the
output so that grep lines in the tests don't unintentionally match
