normal 9d09240d9e rb_execution_context_t: move stack, stack_size and cfp from rb_thread_t
The goal is to reduce rb_context_t and rb_fiber_t size
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.

ko1 76c4cca19c add performance counting mechanism for MRI debug/tuning purpose.
* How to enable this feature?
  * define USE_DEBUG_COUNTER as 1.
  * you can disable to output the result with
    RUBY_DEBUG_COUNTER_DISABLE environment variable
    even if USE_DEBUG_COUNTER == 1.

* How to add new counter?
  * add COUNTER(<name>) line on debug_counter.h.
  * include "debug_counter.h"
  * insert RB_DEBUG_COUNTER_INC(<name>) line on your favorite place.

* counter output example:
  [RUBY_DEBUG_COUNTER]    mc_inline_hit   999
  [RUBY_DEBUG_COUNTER]    mc_inline_miss  3
  [RUBY_DEBUG_COUNTER]    mc_global_hit   23
  [RUBY_DEBUG_COUNTER]    mc_global_miss  273
  [RUBY_DEBUG_COUNTER]    mc_global_state_miss    3
  [RUBY_DEBUG_COUNTER]    mc_class_serial_miss    0
  [RUBY_DEBUG_COUNTER]    mc_cme_complement       0
  [RUBY_DEBUG_COUNTER]    mc_cme_complement_hit   0
  [RUBY_DEBUG_COUNTER]    mc_search_super 1384
  [RUBY_DEBUG_COUNTER]    ivar_get_hit    0
  [RUBY_DEBUG_COUNTER]    ivar_get_miss   0
  [RUBY_DEBUG_COUNTER]    ivar_set_hit    0
  [RUBY_DEBUG_COUNTER]    ivar_set_miss   0
  [RUBY_DEBUG_COUNTER]    ivar_get        431
  [RUBY_DEBUG_COUNTER]    ivar_set        465

  * mc_... is related to method caching.
  * ivar_... is related to instance variable accesses.

* compare with dtrace/system tap features, there are completely
  no performacne penalties when it is disabled.

* This feature is supported only on __GNUC__ compilers.

rhe c54ede0560 proc.c: assume rb_iseq_location_t::first_lineno is always a Fixnum
Do not check for the value of rb_iseq_constant_body::line_info_table as
it is no longer related. The checks seem to be the remains from the day
before the dedicated 'first_lineno' field was introduced. Remove them.

Note, rb_iseq_constant_body::line_info_table can be NULL only when the
iseq does not contain any instructions that originate from Ruby code,
for example, an iseq created with 'proc {}' under a non-default compile
options where trace instructions are disabled.

ko1 9f60791a04 * vm_core.h: revisit the structure of frame, block and env.
[Bug #12628]

  This patch introduce many changes.

  * Introduce concept of "Block Handler (BH)" to represent
    passed blocks.

  * move rb_control_frame_t::flag to ep[0] (as a special local
    variable). This flags represents not only frame type, but also
    env flags such as escaped.

  * rename `rb_block_t` to `struct rb_block`.

  * Make Proc, Binding and RubyVM::Env objects wb-protected.

  Check [Bug #12628] for more details.

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].

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.

normal b49075cdf1 move RB_GC_GUARD responsibility to rb_add_method_iseq
This simplifies all the callers and makes code easier to use
and review.  I was confused about the need for RB_GC_GUARD
in define_{aset,aref}_method of struct.c without reading
rb_add_method_iseq.

Likewise, do the same for rb_iseq_clone, where the GC guard
only seems neccesary iff RGenGC is disabled.

* vm_method.c (rb_add_method_iseq): add RB_GC_GUARD
* class.c (clone_method): remove RB_GC_GUARD
* struct.c (define_aref_method): ditto
  (define_aset_method): ditto
* vm.c (vm_define_method):
* iseq.c (rb_iseq_clone): add RB_GC_GUARD

ko1 7bba6adc56 * vm_method.c (rb_method_entry_create): need to call
method_definition_reset() if def is given.
  Actually, `me' is a new object, so we don't need to call it.
  It is just to make sure.
* vm_method.c (method_definition_reset): remove duplicated insertion.
* vm_method.c (rb_method_entry_clone): assgine dst->def here,
  not in method_definition_reset().
