[PATCH] D147661: [Sema] Tweak merging of availability attributes

I don't think there's a way to test this change, unfortunately. However, I think this exposed a bigger concern, which is that `AttributeCommonInfo` has some single-argument constructors that are not `explicit` so that we don't run into this issue again. However, fixing that entails changing clang's tablegen, so I don't think it should block these changes.
