* method.h: introduce rb_method_definition_t::complemented_count.

Browse source 
* vm_method.c (method_definition_addref_complement): introduced.

  def->alias_count is used to decide warn or do not warn at method
  redefinition. Complented methods should not prevent redefiniton
  warnings.

* vm_method.c (rb_method_definition_release): release def iff
  alias_count == 0 && complemented_count == 0.

* test/ruby/test_module.rb: add a test.
