Patch
This version of the patch is based on some code from Daniel Berlin. Here we
determine which pointers can potentially be associated with a placement new.
We disable TBAA specifically for those pointers.
I'm not 100% confident that this patch always does the right thing. But it
does work for the test cases I tried.
Richi, I'd be interested in results you get from your performance tests.
