* gc.c (Init_stack): avoid __builtin_frame_address(2) to retrieve

  stack bottom line.

* st.c (numhash): should shuffle bits by dividing by prime number.

* eval.c (rb_eval): multiple assignment behavior fixed, which
  results "*a = nil" makes "a == []" now.

* eval.c (rb_f_require): should set SCOPE_PUBLIC before calling
  dln_load().
