Erik Eckstein 62786b01e2 Optimizer: add the mandatory destroy hoisting pass
It hoists `destroy_value` instructions for non-lexical values.

```
  %1 = some_ownedValue
  ...
  last_use(%1)
  ... // other instructions
  destroy_value %1
```
->
```
  %1 = some_ownedValue
  ...
  last_use(%1)
  destroy_value %1    // <- moved after the last use
  ... // other instructions
```

In contrast to non-mandatory optimization passes, this is the only pass which hoists destroys over deinit-barriers.
This ensures consistent behavior in -Onone and optimized builds.
