* bignum.c (Bignum#<=>): remove it because they are unified with

  Integer#<=>.

* numeric.c (Integer#<=>, Fixnum#<=>): move <=> method from Fixnum to
  Integer.

* numeric.c (int_cmp): add this method for Integer#<=>.

* test/-ext-/integer/test_my_integer.rb (test_my_integer_cmp): add a
  test to examine Integer#<=> for unknown subclasses.
