  * Always expose the unfolding of something with an InlineRule
  Ignore-this: 4f952f423848b8840fab69d63ee81d8f
  
  Previously a bottoming function with a strictness wrapper 
  had a hidden inlining, and that was Very Bad, because in 
      f x = if ... then bot_fun x else x+1
  we really want to pass the *unboxed* x to bot_fun. This
  happens quite a bit in error handling code, eg for array
  indexing.
