* configure.in: check function attirbute const and pure,

Browse source 
and define CONSTFUNC and PUREFUNC if available.
  Note that I don't add those options as default because
  it still shows many false-positive (it seems not to consider
  longjmp).

* vm_eval.c (stack_check): get rb_thread_t* as an argument
  to avoid duplicate call of GET_THREAD().
