If the right approach is to split `RecordType` into three independent tablegen
types (`StructType`, `ClassType`, `UnionType`) each with its own grammar,
storage, and printer, I can do that here. It's a larger change since the
mutable-storage mechanism for incomplete types and the custom assembly format
would need to be replicated across all three, but I can take it on in this PR
if that's the direction.
