  * rb_call_info (ci) has compiled fixed information.
  * if ci->flag & VM_CALL_KWARG, then rb_call_info is
    also rb_call_info_with_kwarg. This technique reduce one word
    for major rb_call_info data.
  * rb_calling_info has temporary data (argc, blockptr, recv).
    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.
* insns.def: ditto.
* iseq.c: ditto.
* vm_args.c: ditto.
* vm_eval.c: ditto.
* vm_insnhelper.c: ditto.
* vm_insnhelper.h: ditto.
* iseq.h: add iseq_compile_data::ci_index and
  iseq_compile_data::ci_kw_indx.
* tool/instruction.rb: introduce TS_CALLCACHE operand type.

  overflow checking failed just before/after the beginning of an
  instruction. It should be treated as a BUG.
  Please tell us if your code cause BUG with this problem.
  This check will removed soon (for performance).

  CHECK_STACK_OVERFLOW() to vm_core.h and rename to
  CHECK_VM_STACK_OVERFLOW().
  This change is only move and rename.
* tool/instruction.rb: catch up above changes.
* vm.c, vm_insnhelper.c: ditto.
* vm_insnhelper.c (vm_stackoverflow): add a function to unify
  raising vm stackoverflow exception.
