## Message

```
cbe: Implement wasm builtins

This implements the wasm builtins by lowering to builtins that are supported by c-compilers.
In this case: Clang.

This also simplifies the `AIR` instruction as it now uses the payload field of `ty_pl` and `pl_op`
directly to store the index argument rather than storing it inside Extra. This saves us 4 bytes
per builtin call.

```
