merge revision(s) 38292: [Backport #6899]

	* 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.
