ko1 2108e55c0b use "enum ruby_tag_type" and TAG_NONE.
Return value of EXEC_TAG() is saved by "int state".
Instead of "int", use "enum ruby_tag_type". First EXEC_TAG()
value should be 0, so that define TAG_NONE (= 0) and use it.

Some code used "status" instead of "state". To make them clear,
rename them to state.

We can change variable name from "state" to "tag_state", but this
ticket doesn't contain it.

normal 9d09240d9e rb_execution_context_t: move stack, stack_size and cfp from rb_thread_t

by removing the need to store the entire rb_thread_t in
there.

[ruby-core:81045] Work-in-progress: soon, we will move more fields here.

normal f224fecc0f improve handling of timer thread shutdown
Shutting down the timer thread now always closes pipes to free FDs.
In fact, we close the write ends of the pipes is done in the main
RubyVM to signal the timer thread shutdown.

To effectively close pipes, we implement userspace locks via
atomics to force the pipe closing thread to wait on any signal
handlers which may be waking up.

While we're at it, improve robustness during resource exhaustion and
allow it to limp along non-fatally if restarting a timer thread
fails.

This reverts r51268

ko1 e4198a73d4 * make rb_iseq_t T_IMEMO object (type is imemo_iseq).
All contents of previous rb_iseq_t is in rb_iseq_t::body.
  Remove rb_iseq_t::self because rb_iseq_t is an object.
  RubyVM::InstructionSequence is wrapper object points T_IMEMO/iseq.
  So RubyVM::ISeq.of(something) method returns different wrapper
  objects but they point the same T_IMEMO/iseq object.
  This patch is big, but most of difference is replacement of
  iseq->xxx to iseq->body->xxx.
  (previous) rb_iseq_t::compile_data is also located to
  rb_iseq_t::compile_data.
  It was moved from rb_iseq_body::compile_data.
  Now rb_iseq_t has empty two pointers.
  I will split rb_iseq_body data into static data and dynamic data.
* compile.c: rename some functions/macros.
  Now, we don't need to separate iseq and iseqval (only VALUE).
* eval.c (ruby_exec_internal): `n' is rb_iseq_t (T_IMEMO/iseq).
* ext/objspace/objspace.c (count_imemo_objects): count T_IMEMO/iseq.
* gc.c: check T_IMEMO/iseq.
* internal.h: add imemo_type::imemo_iseq.
* iseq.c: define RubyVM::InstructionSequnce as T_OBJECT.
  Methods are implemented by functions named iseqw_....
* load.c (rb_load_internal0): rb_iseq_new_top() returns
  rb_iseq_t (T_IMEMO/iesq).
* method.h (rb_add_method_iseq): accept rb_iseq_t (T_IMEMO/iseq).
* vm_core.h (GetISeqPtr): removed because it is not T_DATA now.
* vm_core.h (struct rb_iseq_body): remove padding for
  [Bug #10037][ruby-core:63721].

  again.

ko1 5c4d7b9a9e * vm_core.h: remove rb_iseq_t::defined_method_id because it is not
needed.

  has enough information.

ko1 5e8a147480 * method.h: introduce rb_callable_method_entry_t to remove
rb_control_frame_t::klass.
  [Bug #11278], [Bug #11279]
  rb_method_entry_t data belong to modules/classes.
  rb_method_entry_t::owner points defined module or class.
    module M
      def foo; end
    end
  In this case, owner is M.
  rb_callable_method_entry_t data belong to only classes.
  For modules, MRI creates corresponding T_ICLASS internally.
  rb_callable_method_entry_t can also belong to T_ICLASS.
  rb_callable_method_entry_t::defined_class points T_CLASS or
  T_ICLASS.
  rb_method_entry_t data for classes (not for modules) are also
  rb_callable_method_entry_t data because it is completely same data.
  In this case, rb_method_entry_t::owner == rb_method_entry_t::defined_class.
  For example, there are classes C and D, and incldues M,
    class C; include M; end
    class D; include M; end
  then, two T_ICLASS objects for C's super class and D's super class
  will be created.
  When C.new.foo is called, then M#foo is searcheed and
  rb_callable_method_t data is used by VM to invoke M#foo.
  rb_method_entry_t data is only one for M#foo.
  However, rb_callable_method_entry_t data are two (and can be more).
  It is proportional to the number of including (and prepending)
  classes (the number of T_ICLASS which point to the module).
  Now, created rb_callable_method_entry_t are collected when
  the original module M was modified. We can think it is a cache.
  We need to select what kind of method entry data is needed.
  To operate definition, then you need to use rb_method_entry_t.
  You can access them by the following functions.
  * rb_method_entry(VALUE klass, ID id);
  * rb_method_entry_with_refinements(VALUE klass, ID id);
  * rb_method_entry_without_refinements(VALUE klass, ID id);
  * rb_resolve_refined_method(VALUE refinements, const rb_method_entry_t *me);
  To invoke methods, then you need to use rb_callable_method_entry_t
  which you can get by the following APIs corresponding to the
  above listed functions.
  * rb_callable_method_entry(VALUE klass, ID id);
  * rb_callable_method_entry_with_refinements(VALUE klass, ID id);
  * rb_callable_method_entry_without_refinements(VALUE klass, ID id);
  * rb_resolve_refined_method_callable(VALUE refinements, const rb_callable_method_entry_t *me);
  VM pushes rb_callable_method_entry_t, so that rb_vm_frame_method_entry()
  returns rb_callable_method_entry_t.
  You can check a super class of current method by
  rb_callable_method_entry_t::defined_class.
* method.h: renamed from rb_method_entry_t::klass to
  rb_method_entry_t::owner.
* internal.h: add rb_classext_struct::callable_m_tbl to cache
  rb_callable_method_entry_t data.
  We need to consider abotu this field again because it is only
  active for T_ICLASS.
* class.c (method_entry_i): ditto.
* class.c (rb_define_attr): rb_method_entry() does not takes
  defiend_class_ptr.
* gc.c (mark_method_entry): mark RCLASS_CALLABLE_M_TBL() for T_ICLASS.
* cont.c (fiber_init): rb_control_frame_t::klass is removed.
* proc.c: fix `struct METHOD' data structure because
  rb_callable_method_t has all information.
* vm_core.h: remove several fields.
  * rb_control_frame_t::klass.
  * rb_block_t::klass.
  And catch up changes.
* eval.c: catch up changes.
* gc.c: ditto.
* insns.def: ditto.
* vm.c: ditto.
* vm_args.c: ditto.
* vm_backtrace.c: ditto.
* vm_dump.c: ditto.
* vm_eval.c: ditto.
* vm_insnhelper.c: ditto.
* vm_method.c: ditto.
