Thanks @rsmith for the suggestions. I removed the whitelisting totally and changed the strategy. This patch implements your second suggestion which seemed more obvious to me. Since I expect the set of gathered misaligned member designations be small, I am using a plain SmallVector but maybe there is a more suitable structure.

I am now building Firefox and will post an update with the results.
