This will currently accept the old number of bytes syntax, and convert it to a scalar. This should be removed in the near future (I think I converted all of the tests already, but likely missed a few). Not sure what the exact syntax and policy should be. We can continue printing the number of bytes for non-generic instructions to avoid test churn and only allow non-scalar types for generic instructions. This will currently print the LLT in parentheses, but accept parsing the existing integers and implicitly converting to scalar. The parentheses are a bit ugly, but the parser logic seems unable to deal without either parentheses or some keyword to indicate the start of a type.
