<pre>
    Clang analyzer crashes for the following input:
```cpp
void* data = nullptr;
int main() { return __builtin_bit_cast(long, data) + 1; }
```

With a debug build from `main`, I get an assertion of "No dispatcher registered for an event":
```console
$ clang++ -cc1 -analyze -analyzer-checker=nullability.NullReturnedFromNonnull crash.cpp
clang++: /home/fent/llvm-project/clang/lib/StaticAnalyzer/Core/CheckerManager.cpp:56: void clang::ento::CheckerManager::finishedCheckerRegistration(): Assertion `Event.second.HasDispatcher && "No dispatcher registered for an event"' failed.
...
```

This seems related to #60657, but still reproduces on `main` with @steakhal's fix.
