Subject: [PATCH] Update base for Update on "[compiler] Fixture tests for
 PropertyStore effects"

Adds fixture tests to demonstrate an issue in changing PropertyStore to always have a Store effect on its object operand, regardless of the operand type. The issue is that if we're doing a PropertyStore on a nested value, that has be considered a transitive mutation of the parent object:

```
const x = {y: {z: {}}};
x.y.z.key = 'value'; // this has to be a mutation of `x`
```

Fix in the next PR.
