Minimal repro:
```cpp
#include <iostream>
int main() {
auto foo = [a = false]() mutable {
if (a) std::cout << ',';
a = true;
std::cout << 'A';
};
foo();
foo();
}
```

Looks like when `-fexperimental-new-constant-interpreter` is set, `if (a)` condition is optimized away completely, and `-Wunreachable-code` warning is emitted.
Didn't find anything similar in "clang:bytecode" open issues, but feel free to close if this is a duplicate.
