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.

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`.

RCLASS_CALLABLE_M_TBLs of all sub-classes (T_ICLASS).
RCLASS_CALLABLE_M_TBL() caches complemented method entries.
It should be cleared when the modules are cleared.

It is enough for normal modules because corresponding T_ICLASSes

[Feature #11420]
This table only manage ID->VALUE table to reduce overhead of st.
Some functions prefixed rb_id_table_* are provided.
* id_table.c: implement rb_id_table_*.
There are several algorithms to implement it.
Now, there are roughly 4 types:
* st
* array
* hash (implemented by Yura Sokolov)
* mix of array and hash
The macro ID_TABLE_IMPL can choose implementation.
You can see detailes about them at the head of id_table.c.
At the default, I choose 34 (mix of list and hash).
This is not final decision.
Please report your suitable parameters or
your data structure.
* symbol.c: introduce rb_id_serial_t and rb_id_to_serial()
to represent ID by serial number.
* internal.h: use id_table for method tables.
* class.c, gc.c, marshal.c, vm.c, vm_method.c: ditto.

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).

* iseq.c: define RubyVM::InstructionSequnce as T_OBJECT.

* load.c (rb_load_internal0): rb_iseq_new_top() returns

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.

This simplifies all the callers and makes code easier to use
and review. I was confused about the need for RB_GC_GUARD

rb_add_method_iseq.

only seems neccesary iff RGenGC is disabled.

a rb_method_entry_t data (me).
Normally, `me' points `def'. Some Ruby objects pointed from `def'
and objects are marked by `me' (mark_method_entry() in gc.c).
However, `def' is built before making a `me', then nobody can mark
objects pointed from `def' before making (and pointing from) `me'.
I hope this patch solve #11244.
* vm_method.c: remove `rb_' prefix from some static functions.
* method.h (rb_method_entry_create): constify
* gc.c (mark_method_entry): add checking `def' and
`def->body.iseq.iseqptr' availability because they can be NULL.
