* fix the behavior when a module is included into a refinement.
This change is a little tricky, so it might be better to prohibit
module inclusion to refinements.
* include/ruby/ruby.h (RMODULE_INCLUDED_INTO_REFINEMENT): new flag
to represent that a module (iclass) is included into a refinement.
* class.c (include_modules_at): set RMODULE_INCLUDED_INTO_REFINEMENT
if klass is a refinement.
* eval.c (rb_mod_refine): set the superclass of a refinement to the
refined class for super.
* eval.c (rb_using_refinement): skip the above superclass (the
refined class) when creating iclasses for refinements. Otherwise,
`using Refinement1; using Refinement2' creates iclasses:
<Refinement2> -> <RefinedClass> -> <Refinement1> -> RefinedClass,
where <Module> is an iclass for Module, so RefinedClass is
searched before Refinement1. The correct iclasses should be
<Refinement2> -> <Refinement1> -> RefinedClass.
* vm_insnhelper.c (vm_search_normal_superclass): if klass is an
iclass for a refinement, use the refinement's superclass instead
of the iclass's superclass. Otherwise, multiple refinements are
searched by super. For example, if a refinement Refinement2
includes a module M (i.e., Refinement2 -> <M> -> RefinedClass,
and if refinements iclasses are <Refinement2> -> <M>' ->
<Refinement1> -> RefinedClass, then super in <Refinement2> should
use Refinement2's superclass <M> instead of <Refinement2>'s
superclass <M>'.
* vm_insnhelper.c (vm_search_super_method): do not raise a
NotImplementError if current_defind_class is a module included
into a refinement. Because of the change of
vm_search_normal_superclass(), the receiver might not be an
instance of the module('s iclass).
* test/ruby/test_refinement.rb: related test.
