merge revision(s) 44455,44458,44510: [Backport #9349]

* vm_insnhelper.c (vm_search_super_method): direct superclass of a
	  module is found when super called in a Method object generated a
	  method defined in a module, call method_missing in that case.
	  [ruby-core:59358] [Bug #9315]

	* proc.c (mnew_from_me): keep iclass as-is, to make inheritance
	  chain consistent.  [ruby-core:59358] [Bug #9315]

	* proc.c (method_owner): return the original defined_class from
	  prepended iclass, instead.
