In my testing this will need an enhancement on the MSAN side too to understand that `t.~T()` where `T` is a trivial type like `double` would emit `__sanitizer_dtor_callback` (or equivalent) to mark the bytes as poisoned. @vitalybuka could you chime in too on the MSAN side? Just want to make sure libcxx and MSAN folks are on the same page before I proceed.
