methods when called from Kernel#respond_to?. [ruby-dev:40461]

added. Unlinked method entries are collected to
vm->unlinked_method_entry_list. On the GC timing, mark all method
entries which are on all living threads. Only non-marked method
entries are collected. This hack prevents releasing living method
entry.
[Performance Consideration] Since this Method Entry GC (MEGC)
doesn't occuer frequently, MEGC will not be a performance bottleneck.
However, to traverse living method entries, every control frame push
needs to clear cfp->me field. This will be a performance issue
(because pushing control frame is occurred frequently).
Bug #2777 [ruby-dev:40457]
* cont.c (fiber_init): init cfp->me.
* gc.c (garbage_collect): kick rb_sweep_method_entry().
* method.h (rb_method_entry_t): add a mark field.
* vm.c (invoke_block_from_c): set passed me.
* vm.c (rb_thread_mark): mark cfp->me.
* vm_core.h (rb_thread_t): add a field passed_me.
* vm_core.h (rb_vm_t): add a field unlinked_method_entry_list.
* vm_insnhelper.c (vm_push_frame): clear cfp->me at all times.
* vm_insnhelper.c (vm_call_bmethod): pass me.
* bootstraptest/test_method.rb: add a test.

of methods. This is because cfp->me uses the rb_method_entry
which is freed by redefinition of remove_method. Note that
reusing may cause another problem when the usage is changed.

* vm.c, vm_insnhelper.c, vm_method.c, vm_eval.c: ditto. and make some
refactoring.
* insns.def, class.c, eval.c, proc.c, vm_dump.c : ditto.

VM_CALL_SEND_BIT. use another optimization tech for Kernel#send.

* gc.c: add mark/free functions for method entry.
* include/ruby/intern.h: remove decl of
rb_define_notimplement_method_id(). nobody can use it
because noex is not opend.
* iseq.c (iseq_mark): fix to check ic_method is available.
