Fix egregious blunder in the type flattener
In tidying up the flattener I introduced an error that no
regression test caught, giving rise to Trac #8978, #8979.
It shows up if you have a type synonym whose RHS mentions
type functions, such sas
type family F a
type T a = (F a, a) -- This synonym isn't properly flattened
The fix is easy, but sadly the bug is in the released GHC 7.8.1
