    Compute boot-defined TyCon names from ModIface.
    
    Summary:
    Three things in this commit:
    
        1. Get rid of sb_ids; we are not going to use them
        to avoid infinite unfoldings in hs-boot files.
    
        2. Compute sb_tcs from ModIface rather than ModDetails.
        This means that the typechecker can look at this field
        without forcing the boot ModDetails, which would be
        bad if the ModDetails is not available yet (due to
        knot tying.)
    
        3. A big honking comment explaining what is going on
        here.
