* numeric.c (num_finite_p, num_infinite_p): Add Numeric#finite? and
  Numeric#infinite?  [Feature #12039] [ruby-core:73618]

* complex.c (rb_complex_finite_p): Add Complex#finite?

* complex.c (rb_complex_infinite_p): Add Complex#infinite?

* test/ruby/test_bignum.rb: Add test for Integer#finite? and
  Integer#infinite?

* test/ruby/test_fixnum.rb: ditto.
