[PATCH] D30723: Add red zones to BumpPtrAllocator under ASan

Thanks, Pete! Will land soon, then.

> I think we could support SpecificBumpPtrAllocator but it would require walking the objects by 'sizeof(T) + RedZoneSize'. RedZoneSize itself would also have to be set to make sure we continue to have appropriate alignment. Not something you need to do now, but could be interesting in future.

FWIW, this doesn't work as is because SpecificBumpPtrAllocator lets you allocate *arrays* of objects as well as single objects, and the arrays obviously can't have red zones between elements.
