Is it possible to store the stack ID somewhere else?
We can use allocator's metadata (currently, not used in asan at all),
but it will consume extra RAM == bad.
1. Upon INTERCEPTOR(fname) entry, copy the chunk header of every pointer
that fname() can potentially overwrite
Too expensive.
You will have to check if this is a heap (what if not?)
then if it is small heap or larger, then get the header.
