Handle machine stack overflow on mingw

Browse source 
* thread_win32.c (rb_w32_stack_overflow_handler): use Structured
  Exception Handling by Addvectoredexceptionhandler() for machine
  stack overflow on mingw.
  This would be equivalent to the handling using __try and __exept
  on mswin introduced by r43748.
