```
wasm: use liveness analysis for locals

This hooks reusal of locals into liveness analysis.
Meaning that when an operand dies, and is a local,
it will automatically be freed so it can be re-used
when a new local is required. The result of this, is
a lower allocation required for locals. Having less
locals means smaller binary size, as well as faster
compilation speed when loaded by the runtime.

```
