* vm_core.h: split rb_call_info_t into several structs.
* 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. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@51903 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
