  that it is not a current thread.

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.

ko1 478003f6df rename absolute_path to realpath internally and introduce pathobj.
* vm_core.h: rename absolute_path to realpath because it is expected name.
  external APIs (#absolute_path methods) are remained.

* vm_core.h: remove rb_iseq_location_struct::path and
  rb_iseq_location_struct::absolute_path and introduce pathobj.
  if given path equals to given absolute_path (and most of case
  it is true), pathobj is simply given path String. If it is not same,
  pathobj is Array and pathobj[0] is path and pathobj[1] is realpath.

  This size optimization reduce 8 bytes and
  sizeof(struct rb_iseq_constant_body) is 200 bytes -> 192 bytes
  on 64bit CPU.

  To support this change, the following functions are introduced:
    * pathobj_path() (defined in vm_core.h)
    * pathobj_realpath() (ditto)
    * rb_iseq_path() (decl. in vm_core.h)
    * rb_iseq_realpath() (ditto)
    * rb_iseq_pathobj_new() (ditto)
    * rb_iseq_pathobj_set() (ditto)

* vm_core.h (rb_binding_t): use pathobj instead of path. If binding
  is given at eval methods, realpath (absolute_path) was caller's
  realpath. However, they should use binding's realpath.

watson1978 d0015e4ac6 Improve performance of implicit type conversion
To convert the object implicitly, it has had two parts in convert_type() which are
  1. lookink up the method's id
  2. calling the method

Seems that strncmp() and strcmp() in convert_type() are slightly heavy to look up
the method's id for type conversion.

This patch will add and use internal APIs (rb_convert_type_with_id, rb_check_convert_type_with_id)
to call the method without looking up the method's id when convert the object.

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.

normal f11db2a605 vm*: doubly-linked list from ccan to manage vm->living_threads
A doubly-linked list for tracking living threads guarantees
constant-time insert/delete performance with no corner cases of a
hash table.  I chose this ccan implementation of doubly-linked
lists over the BSD sys/queue.h implementation since:

1) insertion and removal are both branchless
2) locality is improved if a struct may be a member of multiple lists
   (0002 patch in Feature 9632 will introduce a secondary list
   for waiting FDs)

This also increases cache locality during iteration: improving
performance in a new IO#close benchmark with many sleeping threads
while still scanning the same number of threads.

* vm_core.h (rb_vm_t): list_head and counter for living_threads
  (rb_thread_t): vmlt_node for living_threads linkage

  vm_memsize, vm_init2, Init_VM): ditto
* vm_trace.c (clear_trace_func_i, rb_clear_trace_func): ditto
* benchmark/bm_vm_thread_close.rb: added to show improvement
* ccan/build_assert/build_assert.h: added as a dependency of list.h

  [ruby-core:61871][Feature 9632 (part 1)]

Apologies for the size of this commit, but I think a good
doubly-linked list will be useful for future features, too.
This may be used to add ordering to a container_of-based hash
table to preserve compatibility if required (e.g. feature 9614).
