poly{,_constraints}: simplify normalize
...
Local function fv doesn't need its first argument.
BTW, the versions in poly and poly_constraints differ in their
usage of fmap vs. map.

poly: fix type inference
...
inferPrim has to apply the substitution when calling unify.
Test case:
\f n -> if True then n else (f (n+1))

Fix type inference in poly.
...
Fixes type checking error in these examples:
Poly> (\x -> if x then x else (x+1))
<<closure>> : Int -> Int
(shouldn't type check)
Poly> (\x -> fix (x 0))
<<closure>> : forall a b. a -> b
(should give forall a. (Int -> a -> a) -> a)
Instead of finding out how to correctly infer types for the
If, Fix and Op cases, this fix delegates to the App case.
