    Better treatment of signatures in cls/inst
    
    The provoking cause for this patch is Trac #5001, comment:23.  There
    was an INLINE pragma in an instance decl, that shouldn't be there.
    But there was no complaint, just a  mysterious WARN later.
    
    I ended up having to do some real refactoring but the result is,
    I think, simpler and more robust.
