compile.c, vm_insnhelper.c: flip-flop without hidden string key

* compile.c (iseq_compile_each): count flip-flop state in local iseq
  not in each iseqs, so that the keys can be other than hidden
  strings.  [ruby-core:47253] [Bug #6899]
* vm_insnhelper.c (lep_svar_get, lep_svar_set, vm_getspecial): store
  flip-flop states in an array instead of a hash.
* iseq.c (set_relation): main iseq also can has local scope.
