commit 35e937973f61a7e5534ecd0b1c67111cd82d4238
Author: Richard Eisenberg <eir at cis.upenn.edu>
Date:   Sat Mar 19 16:55:50 2016 -0400

    Track specified/invisible more carefully.
    
    In particular, this allows correct tracking of specified/invisible
    for variables in Haskell98 data constructors and in pattern synonyms.
    GADT-syntax constructors are harder, and are left until #11721.
    
    This was all inspired by Simon's comments to my fix for #11512,
    which this subsumes.
    
    Test case: ghci/scripts/TypeAppData
    
    [skip ci]  (The test case fails because of an unrelated problem
    fixed in the next commit.)
