Discussions with the OpenACC Standard folks and the dialect folks showed that the ability to have 'set' have a 'device_type' with more than one architecture was a mistake, and one that will be fixed in future revisions of the standard. Since the dialect requires this anyway, we'll implement this in advance of standardization.
