merge revision(s) 4b36a597f48c857aa5eb9ed80fec0d02f6284646: [Backport #17519]

	Fix setting method visibility for a refinement without an origin
	 class

	If a class has been refined but does not have an origin class,
	there is a single method entry marked with VM_METHOD_TYPE_REFINED,
	but it contains the original method entry.  If the original method
	entry is present, we shouldn't skip the method when searching even
	when skipping refined methods.

	Fixes [Bug #17519]
