can we detect annotations like `{-# ANN module "HLint: ignore Reduce duplication" #-}` easily?
Right now this will result (without -fexternal-interpreter or a stage2 compiler) in

  Ignoring ANN annotation, because this is a stage-1 compiler without -fexternal-interpreter or doesn't support GHCi

However, I do not see why this should require the external interpreter at all. This looks to me
more like an informational comment?
