    Tag pointers in interpreted constructors
    
    Instead of stg_interp_constr_entry there are now 7 functions (one for
    each value of the tag bits) that tag the constructor pointer before
    returning. This is consistent with compiled constructors' entry code,
    and expectations that compiled code places on compiled constructors. The
    iserv protocol is extended with an extra field that explains what
    pointer tag the constructor should use.
