Fix GC corruption on macOS and possibly some other OSes
Marking mmap'ed memory as unneeded, leads to it being zeroed out on both Linux and Windows. Unfortunately that behavior is not defined by POSIX, so BSD based OSes (and possible others as well) do not do this. We do however rely on getting zeroed out memory whenever we allocate a new Chunk for the garbage collector. To work around this, zero out memory we deallocate on those platforms.
