This is going to let me just pass through the error struct to the diagnostic rather than having the CRTP and then constructing an info object per CRTP. Currently, to make it easier to refactor, I changed the code in TransferNonSendable to just take in the new error and call the current CRTP routines. In the next commit, I am going to refactor TransferNonSendable.cpp itself. This just makes it easier to test that I did not break anything.
