* vm_insnhelper.h: define struct THROW_DATA to represent

  throwing data. Also define accessor functions.
* eval_intern.h: move related changes into vm_insnhelper.h.
  Now these MACROs (functions) are only used in vm*.c.
  There is only THROW_DATA_P(err) to check this data type or not.
* vm.c: catch up these changes.
* vm_eval.c: ditto.
* vm_insnhelper.c: ditto.
