```
wasm: Use free-lists for unused locals

When a local is no longer needed (for instance, it was used as
a temporary during arithmetic), it can be appended to one of
the typed freelists. This allows us to re-use locals and therefore
require less locals, reducing the binary size, as well as runtime
initialization.

```
