6a1101f23e * include/ruby/ruby.h: support write barrier protection for T_STRUCT. 
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.

  seem good to add.
