  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.

  Introduce the following C APIs:
  * RSTRUCT_RAWPTR(st) returns pointer (do WB on your risk).
    The type of returned pointer is (const VALUE *).
  * RSTRUCT_GET(st, idx) returns idx-th value of struct.
  * RSTRUCT_SET(st, idx, v) set idx-th value by v with WB.
  And
  * RSTRUCT_PTR(st) returns pointer with shady operation.
    The type of returned pointer is (VALUE *).
* struct.c, re.c, gc.c, marshal.c: rewrite with above APIs.
