#7117: Data family constructors defined in GHCi are not in scope

------------------------------+---------------------------------------------
The following example explains the problem:
{{{
> data family Foo a
> data instance Foo Int = FooInt
> :t FooInt
<interactive>:1:1: Not in scope: data constructor `FooInt'
}}}
`FooInt` is defined, but `GHCi` doesn't recognize it.
