HEAD gives warnings about code that it generates itself

The HEAD is now giving warnings about code that it generates itself, e.g.

module Q where

data Foo = Bar Int

gives

$ ghc -fforce-recomp -Wall -fgenerics -c q.hs

q.hs:4:5:
    Warning: Definition but no type signature for `Q.$gtoFoo'
             Inferred type: Q.$gtoFoo :: Int -> Foo

q.hs:4:5:
    Warning: Definition but no type signature for `Q.$gfromFoo'
             Inferred type: Q.$gfromFoo :: Foo -> Int

I assume that this is since the change which added the inferred type to the warning, but I haven't confirmed that.
