* vm_eval.c (vm_call0): fix prototype, the id parameter should be of
	  type ID, not VALUE

	* vm_insnhelper.c (check_match): the rb_funcall family of functions
	  does not care about refinements. We need to use
	  rb_method_entry_with_refinements instead to call === with
	  refinements. Thanks to Jon Conley for reporting this bug.
	  [ruby-core:57051] [Bug #8872]

	* test/ruby/test_refinement.rb: add test
