* vm_trace.c (fill_id_and_klass): TracePoint#defined_class returns
  singleton class. `set_trace_func' passed attached class (which is
  attached/modified by singleton class) by 6th block parameter if it
  is singleton class. Previous behavior follows this spec.
  However, this method named `defined_class' should return singleton
  class directly because singleton methods are defined in singleton
  class. There are no compatible issue because TracePoint is introduced
  after 2.0.
  But compatiblity with `set_trace_func' is brokne. This means that
  you can not replace all `set_trace_func' code with TracePoint
  without consideration of this behavior.
  [Bug #7554]
* test/ruby/test_settracefunc.rb: change a test to catch up
  an above chagne.

* method.h: remove `VM_METHOD_TYPE_CFUNC_FRAMELESS' method type.
  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?).
* proc.c (rb_method_entry_arity): ditto.
* vm_eval.c, vm_insnhelper.c, vm_method.c: ditto.
