When you change this to true, you may need to add more tests.

* test/ruby/test_flip.rb (TestFlip#test_shared_thread): flip-flop
should be separated per threads

* vm_core.h (rb_iseq_t): move flip_cnt from struct iseq_compile_data,
because it has same life span as enclosing iseq. [Bug #7671]
[ruby-core:51296]

* 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.
