Look through calls to std::addressof to compute pointer alignment.

This is sort of a followup to D37310; that basically fixed the same
issue, but then the libstdc++ implementation of <atomic> changed. Re-fix
the the issue in essentially the same way: look through the addressof
operation to find the alignment of the underlying object.
