I think that we should go another way. Firstly we should not use a
static variable here. Please make the NotesMap a member variable of
ScTable. I hope that this solves one part of your problem and then we
should no longer need to make the notes directly available to the
cells. Every information we need should already be available in
ScTable and the idea behind this rework is not only to save a bit
memory per cell but to prepare calc for ixion.

Personally I think we should use another datastructure like
std::map<Address2D, ScPostIt*> or bootst::ptr_map<Address2D, ScPostIt>
but that is something we can figure out later. I think for now it is
more important to move the container to ScTable and make it a member
