```
wasm: Improve memset implementation

When the length is comptime-known, we perform an inline loop instead of emitting
a runtime loop into the binary.

This also allows us to easily write 'undefined' to aggregate types.
We now do this when we set the error tag of an error union where the payload will be set to undefined.

```
