Handle unboxed tuples caused by -funbox-strict-fields

Should we mention this in the README, and perhaps set -fno-unbox-strict-fields in the DynFlagsPlugin (assuming I ever get around to adding it).

Yeah, I can add it to the README when I get around to finding a suitable example. The one we encountered is

Linear.V3.$wcross :: forall a. Num a => a -> a -> a -> a -> a -> a -> (# a, a, a #)

And of course there's no HasRep (# C Double, C Double, C Double #).
