* Fix Trac #1037
It makes *sense* for a foreign import to have a zero-sized return, thus
foreign import ccall foo :: Int -> State# RealWorld
but it's not clear that it's useful, and it requires some back-end (a
Hint for void types) to make it go right through. It's not clear that
we really want this facility, so rather than fixing the code
generator, I'm just making the construct illegal for now.
