Roman Lebedev aa2009fe78 [NFCI][SimplifyCFG] Mark all the SimplifyCFG tests that already don't invalidate DomTree as such
First step after e113317958,
in these tests, DomTree is valid afterwards, so mark them as such,
so that they don't regress.

In further steps, SimplifyCFG transforms shall taught to preserve DomTree,
in as small steps as possible.
