We can return any ISeq object as a result value.
Otherwise loading will be continue as usual.
This interface is not matured and is not extensible.

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).

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.

`flag' contains several categories of attributes and it makes us
confusion (at least, I had confused).
* rb_method_visibility_t (flags::visi)
* NOEX_UNDEF -> METHOD_VISI_UNDEF = 0
* NOEX_PUBLIC -> METHOD_VISI_PUBLIC = 1
* NOEX_PRIVATE -> METHOD_VISI_PRIVATE = 2
* NOEX_PROTECTED -> METHOD_VISI_PROTECTED = 3
* NOEX_SAFE(flag)) -> safe (flags::safe, 2 bits)
* NOEX_BASIC -> basic (flags::basic, 1 bit)
* NOEX_MODFUNC -> rb_scope_visibility_t in CREF
* NOEX_SUPER -> MISSING_SUPER (enum missing_reason)
* NOEX_VCALL -> MISSING_VCALL (enum missing_reason)
* NOEX_RESPONDS -> BOUND_RESPONDS (macro)
Now, NOEX_NOREDEF is not supported (I'm not sure it is needed).
Background:
I did not know what "NOEX" stands for.
I asked Matz (who made this name) and his answer was "Nothing".
"At first, it meant NO EXport (private), but the original
meaning was gone."
This is why I remove the mysterious word "NOEX" from MRI.
* vm_core.h: introduce `enum missing_reason' to represent
method_missing (NoMethodError) reason.
* eval_intern.h: introduce rb_scope_visibility_t to represent
scope visibility.
It has 3 method visibilities (public/private/protected)
and `module_function`.

* vm_insnhelper.c: modify SVAR usage.
When calling ISEQ type method, push CREF information onto method
frame, SVAR located place. Before this fix, SVAR is simply nil.
After this patch, CREF (or NULL == Qfalse for not iseq methods)
is stored at the method invocation.
When SVAR is requierd, then put NODE_IF onto SVAR location,
and NDOE_IF::nd_reserved points CREF itself.

[Feature #10440] (Details are described in this ticket)
Most of complex part is moved to vm_args.c.
Now, ISeq#to_a does not catch up new instruction format.
* vm_core.h: change iseq data structures.
* introduce rb_call_info_kw_arg_t to represent keyword arguments.
* add rb_call_info_t::kw_arg.
* rename rb_iseq_t::arg_post_len to rb_iseq_t::arg_post_num.
* rename rb_iseq_t::arg_keywords to arg_keyword_num.
* rename rb_iseq_t::arg_keyword to rb_iseq_t::arg_keyword_bits.
to represent keyword bitmap parameter index.
This bitmap parameter shows that which keyword parameters are given
or not given (0 for given).
It is refered by `checkkeyword' instruction described bellow.
* rename rb_iseq_t::arg_keyword_check to rb_iseq_t::arg_keyword_rest
to represent keyword rest parameter index.
* add rb_iseq_t::arg_keyword_default_values to represent default
keyword values.
* rename VM_CALL_ARGS_SKIP_SETUP to VM_CALL_ARGS_SIMPLE
to represent
(ci->flag & (SPLAT|BLOCKARG)) &&
ci->blockiseq == NULL &&
ci->kw_arg == NULL.
* vm_insnhelper.c, vm_args.c: rewrite with refactoring.
* rewrite splat argument code.
* rewrite keyword arguments/parameters code.
* merge method and block parameter fitting code into one code base.
* vm.c, vm_eval.c: catch up these changes.
* compile.c (new_callinfo): callinfo requires kw_arg parameter.
* compile.c (compile_array_): check the last argument Hash object or
not. If Hash object and all keys are Symbol literals, they are

"opt_send_without_block".
* parse.y (new_args_tail_gen): reorder variables.
Before this patch, a method "def foo(k1: 1, kr1:, k2: 2, **krest, &b)"
has parameter variables "k1, kr1, k2, &b, internal_id, krest",
but this patch reorders to "kr1, k1, k2, internal_id, krest, &b".

* insns.def (once), vm_insnhelper.c (vm_once_exec): turn the
parameter into a VALUE to get rid of type-punned pointer cast.

* insns.def (opt_aref_with): new instruction to optimize Hash#[],
removing any allocation overhead when used with a string literal
key. Patch by normalperson (Eric Wong). [ruby-core:59640] [Bug #9382]
* insns.def (opt_aset_with): new instruction to optimize Hash#[]=
* compile.c (iseq_compile_each): compiler shortcuts for new
instructions
* hash.c (static VALUE rb_hash_compare_by_id_p): fix documentation for
Hash#compare_by_identity to reflect frozen string sharing
* test/ruby/test_hash.rb (class TestHash): test for new behavior

vm_insnhelper.c, vm_insnhelper.h, vm_method.c: Rename method_serial
to global_method_state and constant_serial to global_constant_state
after discussion with ko1.

method is called on a static string literal with no arguments.
* defs/id.def (firstline): add freeze so idFreeze is available
* insns.def (opt_str_freeze): add opt_str_freeze instruction which
pushes a frozen string literal without allocating a new object if
String#freeze is not overriden
* string.c (Init_String): define String#freeze
* vm.c (vm_init_redefined_flag): define BOP_FREEZE on String class as
a basic operation
* vm_insnhelper.h: ditto

ic_serial. This is possible because these fields are only ever used
exclusively with each other.
* insns.def: ditto
* vm_core.h: ditto
* vm_insnhelper.c: ditto

ruby_vm_global_state_version into two separate counters - one for the
global method state and one for the global constant state. This means
changes to constants do not affect method caches, and changes to
methods do not affect constant caches. In particular, this means
inclusions of modules containing constants no longer globally
invalidate the method cache.
* class.c, eval.c, include/ruby/intern.h, insns.def, vm.c, vm_method.c:
rename rb_clear_cache_by_class to rb_clear_method_cache_by_class
* class.c, include/ruby/intern.h, variable.c, vm_method.c: add
rb_clear_constant_cache
* compile.c, vm_core.h, vm_insnhelper.c: rename vmstat field in
rb_call_info_struct to method_state
* vm_method.c: rename vmstat field in struct cache_entry to method_state

* test/ruby/test_string.rb: Test for above.
* vm.c (vm_init_redefined_flag): Add BOP flag for String#=~
