Constrintern: unified push_name_env and push_loc_name_env; made

location dumping for binders uniformly treated in constrintern.ml (and
renamed the optional arg of interp_context from fail_anonymous to
global_level since the flag now also decides whether to dump binders as
global or local ones); added locations for the variables occurring in
the "as in" clauses;
