RBASIC_CLASS(obj) macro which returns a class of `obj'.
This change is a part of RGENGC branch [ruby-trunk - Feature #8339].
* object.c: add new function rb_obj_reveal().
This function reveal interal (hidden) object by rb_obj_hide().
Note that do not change class before and after hiding.
Only permitted example is:
klass = RBASIC_CLASS(obj);
rb_obj_hide(obj);
....
rb_obj_reveal(obj, klass);
TODO: API design. rb_obj_reveal() should be replaced with others.
TODO: modify constified variables using cast may be harmful for
compiler's analysis and optimizaton.
Any idea to prohibt inserting RBasic::klass directly?
If rename RBasic::klass and force to use RBASIC_CLASS(obj),
then all codes such as `RBASIC(obj)->klass' will be
compilation error. Is it acceptable? (We have similar
experience at Ruby 1.9,
for example "RARRAY(ary)->ptr" to "RARRAY_PTR(ary)".
* internal.h: add some macros.
* RBASIC_CLEAR_CLASS(obj) clear RBasic::klass to make it internal
object.
* RBASIC_SET_CLASS(obj, cls) set RBasic::klass.
* RBASIC_SET_CLASS_RAW(obj, cls) same as RBASIC_SET_CLASS
without write barrier (planned).
* RCLASS_SET_SUPER(a, b) set super class of a.

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.

entry with VM_METHOD_TYPE_REFINED holds only the original method
definition, so ci->me is set to a method entry allocated in the
stack, and it causes SEGV/ILL. In this commit, a method entry
with VM_METHOD_TYPE_REFINED holds the whole original method entry.
Furthermore, rb_thread_mark() is changed to mark cfp->klass to
avoid GC for iclasses created by copy_refinement_iclass().
* vm_method.c (rb_method_entry_make): add a method entry with
VM_METHOD_TYPE_REFINED to the class refined by the refinement if
the target module is a refinement. When a method entry with
VM_METHOD_TYPE_UNDEF is invoked by vm_call_method(), a method with
the same name is searched in refinements. If such a method is
found, the method is invoked. Otherwise, the original method in
the refined class (rb_method_definition_t::body.orig_me) is
invoked. This change is made to simplify the normal method lookup
and to improve the performance of normal method calls.
* vm_method.c (EXPR1, search_method, rb_method_entry),
vm_eval.c (rb_call0, rb_search_method_entry): do not use
refinements for method lookup.
* vm_insnhelper.c (vm_call_method): search methods in refinements if
ci->me is VM_METHOD_TYPE_REFINED. If the method is called by
super (i.e., ci->call == vm_call_super_method), skip the same
method entry as the current method to avoid infinite call of the
same method.
* class.c (include_modules_at): add a refined method entry for each
method defined in a module included in a refinement.
* class.c (rb_prepend_module): set an empty table to
RCLASS_M_TBL(klass) to add refined method entries, because
refinements should have priority over prepended modules.
* proc.c (mnew): use rb_method_entry_with_refinements() to get
a refined method.
* vm.c (rb_thread_mark): mark cfp->klass for iclasses created by
copy_refinement_iclass().
* vm.c (Init_VM), cont.c (fiber_init): initialize th->cfp->klass.
* test/ruby/test_refinement.rb (test_inline_method_cache): do not skip
the test because it should pass successfully.
* test/ruby/test_refinement.rb (test_redefine_refined_method): new
test for the case a refined method is redefined.

This method is similar to VM_METHOD_TYPE_CFUNC methods, but
called cfunc without building new frame (does not push new control
frame). If error is occured in cfunc, the backtrace only shows
caller frame and upper.
This kind of methods can be added by rb_define_method_fast().
This feature is similar to specialized instructions (opt_plus, etc),
but more flexible (but a bit slower).
* class.c (rb_define_method_fast): added.
Maybe it will be renamed soon.
* vm_insnhelper.c (vm_call_method): support method type
VM_METHOD_TYPE_CFUNC_FAST.
