Fix GC_get_thr_restart_signal for Darwin and Win32

* misc.c (GC_get_thr_restart_signal): Implement for Darwin and Win32
(always returns -1) if THREADS.
* pthread_stop_world.c (GC_get_thr_restart_signal): Remove
implementation for Darwin/Win32 (since the file might not be included
for these targets).
