Roman Lebedev 570b485d61 [CodeGen][SimplifyCFG] Teach DwarfEHPrepare to preserve DomTree
Once the default for SimplifyCFG flips, we can no longer pass nullptr
instead of DomTree to SimplifyCFG, so we need to propagate it here.

We don't strictly need to actually preserve DomTree in DwarfEHPrepare,
but we might as well do it, since it's trivial.
