I’ve added a test for the `if (auto x = something)` case  let me know if it 
looks good now! 
I didn’t include the `if (auto x = something; x.something_else)` style yet 
because I was thinking of doing something like:

```cpp
int if_init_and_cond() {
  if (int x = 42; x > 0) {
    return x + 2;
  } else {
    return x - 2; 
  }
}
```

but `x > 0` fails with BinaryOperator Not Yet Implemented:  

If `if (int x = 42; true)` is good enough for now, I can go ahead and add a 
test for that too  just let me know what you prefer.
