[PATCH] D32456: [ubsan] Make the alignment check work with some extern decls (PR32630)

[Eli Friedman via Phabricator via cfe-commits]

efriedma added a comment.

This should work correctly with alignment attributes, I think?  IIRC those just change the return value of getDeclAlign().

I agree it's a little fragile, but I don't have a good suggestion to avoid that.
