## Message

```
wasm: Store stack-offset as WValue

Rather than using runtime to perform pointer arithmetic to set the stack offset as
a pointer into a local, we now store the offset as a WValue from the bottom of the stack.
This has the benefit of less instructions, few locals, and less performance impact when
we allocate a value on the virtual stack.
