RARRAY_RAWPTR(ary) returns (const VALUE *) type pointer and
usecase of this macro is not acquire raw pointer, but acquire
read-only pointer. So we rename to better name.
RSTRUCT_RAWPTR() is also renamed to RSTRUCT_CONST_PTR()
(I expect that nobody use it).

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)".

This method type is for optimized CFUNC such as Fixnum#+ and so on.
This feature is half-baked and no way to use them.
[Background]
Now, VM has opt_plus instructions to optimize `+' methods for
some Classes (such as Fixnum, Float (flonum)). We call this
type of instructions as `specialized instructions'.
This simple technique improve simple program dramatically.
However, we can make specialized instructions for only several
types (classes) and selectors (method names) because a large
instruction will be slow. In other words, this technique has no
extensibility.
To overcome this problem, VM_METHOD_TYPE_CFUNC_FRAMELESS was
introduced (r37198). This type is a variant of CFUNC, but called
their functiions directly without building a method frame.
Any CFUNC method can be defined as frameless methods if a method
is not needed to make method frame. Frameless methods are faster
as specialized instructions (a bit slower, but no need to care).
No problem described at
http://charlie.bz/blog/why-do-singleton-methods-make-ruby-slow
because this technique doesn't see class, but see method body
itself. Alias is also no problem.
[Problem]
However, we can't set frameless method type for polymorphic methods
such as Array#[]. Necessity for method frame depends on which
parameter type. For example, Fixnum#+ needs method frame if
coerce is needed. Current VM_METHOD_TYPE_CFUNC_FRAMELESS is not
flexible and need more tuning to introduce it.
Expected behavior of frameless method type may be:
result = optimized_cfunc(params); /* call optimized cfunc */
if (result == Qundef) { result = normal_cfunc(); }
This is why I say this feature is half-baked.
We need to learn primitive method in Smalltalk more.
(I heard this name at RubyConf Taiwan this month. Thanks!)
[Conclusion]
Nobody may use this feature and there is no compatibility issue.
This feature goes to next minor (2.1?).

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.
