Subject: check an existence of block.

* gc.c (rb_raw_obj_info): check block before using it.

* vm_core.h (vm_block_iseq): r61565 introduced NULL check but this
  check is only needed by `rb_raw_obj_info()` and it is called at GC
  debug mode. Above fix for `rb_raw_obj_info()` solves this problem and
  NULL check should not be needed any more.
