also rb_call_info_with_kwarg. This technique reduce one word

for each method dispatch. This data is allocated only on
machine stack.
* rb_call_cache is for inline method cache.
Before this patch, only rb_call_info_t data is passed.
After this patch, above three structs are passed.
This patch improves:
* data locarity (rb_call_info is now read-only data).
* reduce memory consumption (rb_call_info_with_kwarg,
rb_calling_info).
* compile.c: use above data.

string literals.
[Feature #11473]
This addition is not specification change, but to try frozen
string literal world discussed on [Feature #11473].
You can try frozen string literal world using this magical line:
RubyVM::InstructionSequence.compile_option =
{frozen_string_literal: true}
Note that this is a global compilation option, so that you need to
compile another script like that:
p 'foo'.frozen? #=> false
RubyVM::InstructionSequence.compile_option =
{frozen_string_literal: true}
p 'foo'.frozen? #=> false, because this line is already compiled.
p eval("'foo'.frozen?") #=> true
Details:
* String literals are deduped by rb_fstring().
* Dynamic string literals ("...#{xyz}...") is now only frozen,
not deduped. Maybe you have other ideas.
Now, please do not use this option on your productions :)
Of course, current specification can be changed.
* compile.c: ditto.
* test/ruby/test_iseq.rb: add a test.

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
