* vm_core.h (rb_vm_t), vm.c (rb_vm_mark): moved preallocated special

  exceptions.

* eval.c (Init_eval), gc.c (Init_GC), proc.c (Init_Proc): freeze
  preallocated special exceptions.

* eval.c (rb_longjmp): duplicate the thrown exception to set backtrace
  if it was frozen.

* gc.c (rb_memerror): raise nomem_error without backtrace if failed to
  make backtrace.
