    Test for newtype with unboxed argument
    
    Newtypes cannot (currently) have an unboxed argument type.
    But Trac #12729 showed that this was only being checked for
    newtypes in H98 syntax; in GADT snytax they were let through.
    
    This patch moves the test to checkValidDataCon, where it properly
    belongs.
