  [NFC] StackProtector: be consistent and to initialize DominatorTreeWrapperPass

We already ask for it, so it might be good to ensure that it is
actually initialized before us. Doesn't seem to matter in practice though.

  -----------
  [CodeGen] SafeStack: preserve DominatorTree if it is avaliable

While this is mostly NFC right now, because only ARM happens
to run this pass with DomTree available before it,
and required after it, more backends will be affected once
the SimplifyCFG's switch for domtree preservation is flipped,
and DwarfEHPrepare also preserves the domtree.
