When adding new attributes, existing attributes are dropped. While this appears to be a longstanding issue, this was highlighted by D105169 which dropped a lot of attributes due to adding the new noundef attribute. Ahmed Bougacha (@ab) tracked down the issue and provided the fix in CGCall.cpp. I bundled it up and updated the tests.
