----------------
Could you please either create _fuchsia.cc file or 
consolidate code into single #if

e.g.:


```
#if SANITIZER_FUCHSIA 

void InitializeDeadlySignals() {}

#else

static void OnStackUnwind(const SignalContext &sig, const void *,
                          BufferedStackTrace *stack) {
...
}

static void UBsanOnDeadlySignal(int signo, void *siginfo, void *context) {
...
}
static bool is_initialized = false;

void InitializeDeadlySignals() {
  if (is_initialized)
    return;
  is_initialized = true;
  InitializeSignalInterceptors();
  InstallDeadlySignalHandlers(&UBsanOnDeadlySignal);
}

#endif 
```
