## Message

```
spirv: add type_map to map AIR types to SPIR-V types

This will help us both to make the implementation a little
more efficient by caching emission for certain types like structs,
and also allow us to attach extra information about types that we
can use while lowering without performing a search over the entire
type tree for some property.
