Parameterized modules don't consider their own type contraints

[weaversa]

This was happily accepted via version 2.10 but not with the current 2.11 nightly. @yav ?

$  more test.cry
module test where

parameter

  type a : #
  type constraint (fin a, a >= 1)

  b : Z a

$ cryptol test.cry

    in the definition of 'test::b', at test.cry:8:3--8:4,
    we need to show that
