Add a frozenness check to Enumerator#initialize.

* enumerator.c (enumerator_init): Add a frozenness check to
  prevent a frozen Enumerator object from being reinitialized with
  a different enumerable object.  This is the least we should do,
  and more fixes will follow. [Fixes GH-368] Patch by Kenichi
  Kamiya.

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().

* hash.c (rb_hash_assoc): performance improvement by replacing
  compare function in RHASH(hash)->ntbl->type temporarily like r42224.
  it falls back to rb_hash_foreach() if st_lookup() doesn't find the key.

* test/ruby/test_hash.rb: add a test for above.
