 Fix the instantiation of data constructors in the GHCi debugger

 This bug caused Trac #7386, because in the (rather tricky) type
 inference (aka run time type reconstruction) done by the GHCi
 debugger, we were failing to instantiate a data type family
 correctly.  When that code was written we didn't *have* data
 families.

 I wrote Note [Constructor arg types] to explain the new scheme.
