 In [changeset:"f2a2b79fa8d1c702b17e195a70734b06625e0153/ghc"

 Deeply instantiate in :type

 See Trac #11376 and
  Note [Deeply instantiate in :type] in TcRnDriver

 Sadly this showed up one new problem (Trac #11786) and one opportunity
 (Trac #11787), so test T11549 is now marked expect-broken on these two.
