TypeDecls (alias, structure) are not a types - they declare types. ast::TypeName is what's used for a ast::Type. Previously we were trying to automatically convert these to TypeNames in the builder, but having these inherit from ast::Type was extremely error prone. reader/spirv was actually constructing ast::Structs and using them as types, which is invalid.
