Fix Trac #3391: make generic to/from bindings only for newly-declared types

Before this patch we were bogusly making to/from bindings for all data types
in the TcGblEnv.  But that is wrong when we have multiple "chunks" of
bindings in Template Haskell.  We should start from the declarations
themselves.  Easy.
