AllocId
they belong to.source§type ProvenanceExtra = bool

that is passed to memory access hooks so they can do things with it.
source§type ExtraFnVal = !

dlsym
that can later be called to execute the right thing.source§type MemoryMap = IndexMap<AllocId, (MemoryKind<!>, Allocation), BuildHasherDefault<FxHasher>>
