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.

make all Float objects frozen.
[ruby-dev:46081] [ruby-trunk - Feature #6936]
Most part of patch by NARUSE, Yui <naruse@ruby-lang.org>.
* class.c (singleton_class_of): raise TypeError when
trying to define a singleton method on Float objects.
* vm.c (vm_define_method): ditto.
* test/ruby/marshaltestlib.rb: catch up above changes.
* test/ruby/test_class.rb: ditto.
* test/test_pp.rb: ditto.

`rb_add_method_cfunc_frameless()' API.
This API is not mature to become an offical API.
For example, we can not use this API with
`rb_define_private_method()'.
* method.h, vm_method.c (rb_add_method_cfunc_frameless): removed.

rb_define_method_fast(). Defined method with this C API
does not make a method frame. It is bit lightweight than
ordinal C functions. Now only 0 or 1 argc are permitted.
* method.h (VM_METHOD_TYPE_CFUNC_FRAMELESS): rename macro name
from VM_METHOD_TYPE_CFUNC_FAST.
* vm_insnhelper.c, vm_method.c: rename related functions.
* proc.c (rb_method_entry_arity): catch up above changes.

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.
* proc.c (rb_method_entry_arity): catch up new method type.
* vm_method.c (rb_add_method_cfunc_fast): added.

* class.c (rb_special_singleton_class_of): utility function.
* vm_eval.c (eval_under): special deal for class variable scope with
instance_eval.
* vm_eval.c (rb_obj_instance_eval, rb_obj_instance_exec): allow method
definition in instance_eval of special constants. [ruby-core:28324]

vm_insnhelper.c: use struct rb_constant_entry_t as entry of
RCLASS_CONST_TBL. RCLASS_CONST_TBL has contained VALUE of constant
directly. Now instead rb_const_entry_t is contained in
RCLASS_CONST_TBL, rb_const_entry_t is managed by malloc, and
have not only the value itself but also visibility flag.
This is another preparation for private constant (see
[ruby-dev:39685][ruby-core:32698]).
