Subject: [PATCH] Add a frozenness check test for Enumerator::Lazy#initialize.
* test/ruby/test_lazy_enumerator.rb
(TestLazyEnumerator#test_initialize): Make sure
Enumerator::Lazy#initialize raises error if the object is
frozen. The check was performed by rb_ivar_set() before
rb_check_frozen() was added to enumerator_init().
