Generic storage class is enabled with a Addresses capability aka non-default. I'm fine with such behavior, but would be nice to hear from people work on Shader SPIR-V what would the prefer as the default, @VyacheslavLevytskyy may I ask you to tag them here?

also a nit: 8 -> StorageClass::Generic (or other appropriate enum value defined for SPIR-V backend)
