commit 24f6bec94411aa6c39a2c94ce5154ffe96ae330f
Author: Edward Z. Yang <ezyang at cs.stanford.edu>

    Sanity check if we pick up an hsig file without -instantiated-with.
    
    Summary:
    Previously we would just let compilation proceed along until
    we tried to pull up the Module for the hsig file, and get
    main:A instead of <A>, and get a mysterious error.  Check
    for this earlier!
    
    Fixes #12955.
