* vm_core.h (rb_thread_t): new member machine_stack_maxsize and

  machine_register_stack_maxsize.

* gc.c (rb_gc_stack_maxsize): new global variable for the thread size
  of the main thread.
  (STACK_LEVEL_MAX): use machine_stack_maxsize of current thread.
  (ruby_stack_check): check IA64 register stack.
  (ruby_set_stack_size): set rb_gc_stack_maxsize.
  (Init_stack): set rb_gc_stack_maxsize.

* thread_pthread.ci (native_thread_create): initialize
  th->machine_stack_maxsize and th->machine_register_stack_maxsize.

* vm.c (Init_BareVM): initialize th->machine_stack_maxsize and
  th->machine_register_stack_maxsize.

* thread_win32.ci (native_thread_create): initialize
  th->machine_stack_maxsize.  not tested.  just a guess at all.
