* bignum.c (Bignum#even?, Bignum#odd?): remove definitions

because they are unified with Integer#even? and Integer#odd?.

* numeric.c (Fixnum#zero?, Fixnum#even?, Fixnum#odd?): remove
  definitions because they are unified with Numeric#zero?,
  Integer#even?, and Integer#odd?.

* numeric.c (num_zero_p, int_even_p, int_odd_p): treat Fixnum and
  Bignum values directly.

* test/ruby/test_integer.rb (test_odd_p_even_p): remove meaningless
  test case.
