* vm_insnhelper.h: use T_IMEMO to create THROW_DATA.

  Add THROW_DATA_NEW().
* internal.h: move defnition of `struct THROW_DATA'
  from vm_insnhelper.h to internal.h.
  Rename `THROW_DATA' to `vm_throw_data'.
* eval_intern.h (THROW_DATA_P): move to internal.h.
  THROW_DATA is no longer T_NODE, so check T_IMEMO.
* gc.c (gc_mark_children): mark THROW_DATA.
* vm.c: catch up these changes.
* vm_eval.c: ditto.
* vm_insnhelper.c: ditto.
