Vacuum unused values (#1918)
Checks if a value is being dropped higher up, like
```
(drop
(block i32
(block i32
(i32.const 1)
)
)
)
```
Handling this forces us to be careful in that pass about whether a value is used, and whether the type matters (for example, we can't replace a unary with its child in all cases, if the return value matters).
