* add RUBY_TYPED_FREE_IMMEDIATELY to data types which only use

  safe functions during garbage collection such as xfree().
  On default, T_DATA objects are freed at same points as fianlizers.
  This approach protects issues such as reported by [ruby-dev:35578].
  However, freeing T_DATA objects immediately helps heap usage.
  Most of T_DATA (in other words, most of dfree functions) are safe.
  However, we turned off RUBY_TYPED_FREE_IMMEDIATELY by default
  for safety.
