cp-gimplify.c: Include pointer-set.h

2004-11-15  Andrew Pinski  <pinskia@physics.uc.edu>

        * cp-gimplify.c: Include pointer-set.h
        (cp_genericize_r): Use pointer_sets instead of a hashtable.
        Also instert the new statement for CLEANUP_STMT.
        (cp_genericize): Use pointer_sets instead of a hashtable.
        * Make-lang.in (cp-gimplify.o): Depend on pointer-set.h.
