  Added files:
    ruby:
      ia64.s
  Log:
    * configure.in: define IA64 for portability.  (HP aC++/ANSI C doesn't
      define __ia64__.)
      don't check libunwind stuff.
      check __libc_ia64_register_backing_store_base.
    
    * defines.h: declare rb_ia64_bsp and rb_ia64_flushrs.
      (flush_register_windows): call rb_ia64_flushrs on IA64.
    
    * ia64.s: new file for IA64.
      it is separated from C program files because
      Intel C++ Compiler for IA64 doesn't support inline assembly.
    
    * common.mk (ia64.$(OBJEXT)): new target.
    
    * ruby.h (RUBY_INIT_STACK): defined.
      (ruby_init_stack): declared for RUBY_INIT_STACK.
    
    * main.c (main): precedes RUBY_INIT_STACK before ruby_init.
    
    * gc.c (rb_gc_register_stack_start): new global variable on IA64.
      (garbage_collect): simplify register stack marking code.
      don't use libunwind.
      (Init_stack): initialize rb_gc_register_stack_start.
      (ruby_init_stack): new function for RUBY_INIT_STACK.
    
    * eval.c (struct thread): add bstr_pos member for original position of
      register stack.
      (rb_thread_save_context): simplify register stack saving code.
      don't use libunwind.
      (rb_thread_restore_context_0): new function.  moved from
      rb_thread_restore_context except the stack position checking code.
      don't use libunwind for IA64 register stack.
      (register_stack_extend): new function.
      (stack_extend): make it self-recursive with
      the stack position checking code in old rb_thread_restore_context.
      (rb_thread_restore_context): just call stack_extend.
      (flush_register_windows): removed.
