Thanks @jcking, this mostly makes sense. I understand you're mostly looking to keep a 1:1 relationship between user-level operators (new, free, free_sized, etc.) and their asan interceptors. This checks out.

What I don't understand is this comment:

> Right now memalign is used for all the AllocType and we are about to introduce FROM_ALIGNED_ALLOC

This doesn't seem 100% right now. As per your refactor, aren't all interceptors "right now"/today used for all `AllocType`? I don't understand what makes memaligned special.
