 `RetainerProfile:isRetainer` has a switch on closure types which appears
 to be lacking several defined types.

  * `BLOCKING_QUEUE`: someone actually came into `#ghc` complaining about a
 crash due to this one
  * `WHITEHOLE`
  * `SMALL_MUT_ARR_PTRS_CLEAN`
  * `SMALL_MUT_ARR_PTRS_DIRTY`
  * `SMALL_MUT_ARR_PTRS_FROZEN0`
  * `SMALL_MUT_ARR_PTRS_FROZEN`
  * `COMPACT_NFDATA`
