When a Swift declaration witnesses an ObjC protocol requirement, its error convention needs to match the requirement. Furthermore, if there are different protocol requirements that the Swift method can witness, with different error conventions, we need to bail out because we can't simultaneously match all of them. Fixes rdar://problem/59496036 | SR-12201.
