Ah nice was not aware that this was allowed without checking (I believe there was/is another place I copied this from). 

LGTM. And if this wasn't NFC it would have noticed by the tests.


I can see a few other placs that check for `MAI->hasDotTypeDotSizeDirective()` before calling emitSymbolAttribute(). Should those be simplified as well as part of this PR or as a separate one?
