Hack from Simon: put abstract type decls (i.e. from an hi-boot file)
on the defferred list, just in case we happen to pull in the real one
as well.

-- HACK ALERT! If the data type is abstract then it must from a
-- hand-written hi-boot file. We put it in the deferred pile unconditionally,
-- because we don't want to read it in, and then later find a decl for a constructor
