* thread.c (rb_gc_save_machine_context): don't save the stack pointer 

in this function.
  (RB_GC_SAVE_MACHINE_CONTEXT): call rb_gc_save_machine_context and
  save the stack pointer at caller side.
  (rb_thread_schedule_rec): use RB_GC_SAVE_MACHINE_CONTEXT instead of
  rb_gc_save_machine_context.
  (blocking_region_begin): changed to a macro.  use
  RB_GC_SAVE_MACHINE_CONTEXT instead of rb_gc_save_machine_context.
