[PATCH] D32378: Insert invariant.group.barrier for pointers comparisons

[Piotr Padlewski via Phabricator via cfe-commits]

Prazek added a comment.

This is actually good catch, we also need to do it when inserting barrier in placement new. 
I think that for the ctors and dtors we can do it only with optimizations enabled, because if optimizations are not enabled then ctors and dtors won't have the invariant.group in stores.
