  [NFC][EntryExitInstrumenter] Mark Dominator Tree as preserved in legacy-PM too

This is correctly handled in new-PM wrappers, but not in old-PM.

  [PartiallyInlineLibCalls] Preserve Dominator Tree, if avaliable

This doesn't get rid of any Dominator Tree recalculations just yet,
there is one more pass to update..

  Log Message:
  -----------
  [ScalarizeMaskedMemIntrin] Preserve Dominator Tree, if avaliable

This de-pessimizes the arguably more usual case of no masked mem intrinsics,
and gets rid of one more Dominator Tree recalculation.

As per llvm/test/CodeGen/X86/opt-pipeline.ll,
there's one more Dominator Tree recalculation left, we could get rid of.
