vm.c (rb_thread_mark): mark a working Proc of bmethod
(a method defined by define_method) even if the method was removed.
We could not trace working Proc object which represents the body
of bmethod if the method was removed (alias/undef/overridden).
Simply, it was mark miss.
This patch by Kazuki Tsujimoto. [Bug #7825]
NOTE: We can brush up this marking because we do not need to mark me' on each living control frame. We need to mark me's
only if `me' was free'ed. This is future work after Ruby 2.0.0.
