## Message

```
wasm: airAggregateInit - Support packed structs

This allows the Wasm backend to construct an instance of a packed
struct during runtime. We first allocate a local, and then
shift+or each field's value into the result local. We then finally
return this result local as value.

The commit also fixes a type-issue in `airElemVal` where we used
the element type instead of a pointer type to store the value's
address into.
