* 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.
